-## Installation
-
-### Go
-
-If you have a [Golang][golang] environment setup, you can simply run:
-
-```bash
-go get -u -v github.com/go-task/task/cmd/task
-```
-
-### Homebrew
-
-If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
-as simple as running:
-
-```bash
-brew update
-brew tap go-task/tap
-brew install go-task
-```
-
-### Snap
-
-Task is available for [Snapcraft][snapcraft], but keep in mind that your
-Linux distribution should allow classic confinement for Snaps to Task work
-right:
-
-```bash
-sudo snap install task
-```
-
-### Binary
-
-Or you can download the binary from the [releases][releases] page and add to
-your `PATH`. DEB and RPM packages are also available.
-The `task_checksums.txt` file contains the sha256 checksum for each file.
-
-## Usage
-
-Create a file called `Taskfile.yml` in the root of the project.
-The `cmds` attribute should contains the commands of a task.
-The example below allows compile a Go app and uses [Minify][minify] to concat
-and minify multiple CSS files into a single one.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-Running the tasks is as simple as running:
-
-```bash
-task assets build
-```
-
-Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
-interpreter. So you can write sh/bash commands and it will work even on
-Windows, where `sh` or `bash` is usually not available. Just remember any
-executable called must be available by the OS or in PATH.
-
-If you ommit a task name, "default" will be assumed.
-
-### Environment
-
-You can specify environment variables that are added when running a command:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo $hallo
-    env:
-      hallo: welt
-```
-
-### OS specific task
-
-If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your taskfile
-based on the operating system.
-
-Example:
-
-Taskfile.yml:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo "default"
-```
-
-Taskfile_linux.yml:
-
-```yml
-tasks:
-  build:
-    cmds:
-      - echo "linux"
-```
-
-Will print out `linux` and not default.
-
-It's also possible to have OS specific `Taskvars.yml` file, like
-`Taskvars_windows.yml`, `Taskfile_linux.yml` or `Taskvars_darwin.yml`. See the
-[variables section](#variables) below.
-
-### Task directory
-
-By default, tasks will be executed in the directory where the Taskfile is
-located. But you can easily make the task run in another folder informing
-`dir`:
-
-```yml
-version: '2'
-
-tasks:
-  serve:
-    dir: public/www
-    cmds:
-      # run http server
-      - caddy
-```
-
-### Task dependencies
-
-You may have tasks that depends on others. Just pointing them on `deps` will
-make them run automatically before running the parent task:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    deps: [assets]
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-In the above example, `assets` will always run right before `build` if you run
-`task build`.
-
-A task can have only dependencies and no commands to group tasks together:
-
-```yml
-version: '2'
-
-tasks:
-  assets:
-    deps: [js, css]
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-If there are more than one dependency, they always run in parallel for better
-performance.
-
-If you want to pass information to dependencies, you can do that the same
-manner as you would to [call another task](#calling-another-task):
-
-```yml
-version: '2'
-
-tasks:
-  default:
-    deps:
-      - task: echo_sth
-        vars: {TEXT: "before 1"}
-      - task: echo_sth
-        vars: {TEXT: "before 2"}
-    cmds:
-      - echo "after"
-
-  echo_sth:
-    cmds:
-      - echo {{.TEXT}}
-```
-
-### Calling another task
-
-When a task has many dependencies, they are executed concurrently. This will
-often result in a faster build pipeline. But in some situations you may need
-to call other tasks serially. In this case, just use the following syntax:
-
-```yml
-version: '2'
-
-tasks:
-  main-task:
-    cmds:
-      - task: task-to-be-called
-      - task: another-task
-      - echo "Both done"
-
-  task-to-be-called:
-    cmds:
-      - echo "Task to be called"
-
-  another-task:
-    cmds:
-      - echo "Another task"
-```
-
-Overriding variables in the called task is as simple as informing `vars`
-attribute:
-
-```yml
-version: '2'
-
-tasks:
-  main-task:
-    cmds:
-      - task: write-file
-        vars: {FILE: "hello.txt", CONTENT: "Hello!"}
-      - task: write-file
-        vars: {FILE: "world.txt", CONTENT: "World!"}
-
-  write-file:
-    cmds:
-      - echo "{{.CONTENT}}" > {{.FILE}}
-```
-
-The above syntax is also supported in `deps`.
-
-### Prevent unnecessary work
-
-If a task generates something, you can inform Task the source and generated
-files, so Task will prevent to run them if not necessary.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    deps: [js, css]
-    cmds:
-      - go build -v -i main.go
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-    sources:
-      - src/js/**/*.js
-    generates:
-      - public/script.js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-    sources:
-      - src/css/**/*.css
-    generates:
-      - public/style.css
-```
-
-`sources` and `generates` can be files or file patterns. When both are given,
-Task will compare the modification date/time of the files to determine if it's
-necessary to run the task. If not, it will just print a message like
-`Task "js" is up to date`.
-
-If you prefer this check to be made by the content of the files, instead of
-its timestamp, just set the `method` property to `checksum`.
-You will probably want to ignore the `.task` folder in your `.gitignore` file
-(It's there that Task stores the last checksum).
-This feature is still experimental and can change until it's stable.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build .
-    sources:
-      - ./*.go
-    generates:
-      - app{{exeExt}}
-    method: checksum
-```
-
-> TIP: method `none` skips any validation and always run the task.
-
-Alternatively, you can inform a sequence of tests as `status`. If no error
-is returned (exit status 0), the task is considered up-to-date:
-
-```yml
-version: '2'
-
-tasks:
-  generate-files:
-    cmds:
-      - mkdir directory
-      - touch directory/file1.txt
-      - touch directory/file2.txt
-    # test existence of files
-    status:
-      - test -d directory
-      - test -f directory/file1.txt
-      - test -f directory/file2.txt
-```
-
-You can use `--force` or `-f` if you want to force a task to run even when
-up-to-date.
-
-Also, `task --status [tasks]...` will exit with non-zero exit code if any of
-the tasks is not up-to-date.
-
-### Variables
-
-When doing interpolation of variables, Task will look for the below.
-They are listed below in order of importance (e.g. most important first):
-
-- Variables declared locally in the task
-- Variables given while calling a task from another.
-  (See [Calling another task](#calling-another-task) above)
-- Variables declared in the `vars:` option in the `Taskfile`
-- Variables available in the `Taskvars.yml` file
-- Environment variables
-
-Example of sending parameters with environment variables:
-
-```bash
-$ TASK_VARIABLE=a-value task do-something
-```
-
-Since some shells don't support above syntax to set environment variables
-(Windows) tasks also accepts a similar style when not in the beginning of
-the command. Variables given in this form are only visible to the task called
-right before.
-
-```bash
-$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
-```
-
-Example of locally declared vars:
-
-```yml
-version: '2'
-
-tasks:
-  print-var:
-    cmds:
-      echo "{{.VAR}}"
-    vars:
-      VAR: Hello!
-```
-
-Example of global vars in a `Taskfile.yml`:
-
-```yml
-version: '2'
-
-vars:
-  GREETING: Hello from Taskfile!
-
-tasks:
-  greet:
-    cmds:
-      - echo "{{.GREETING}}"
-```
-
-Example of `Taskvars.yml` file:
-
-```yml
-PROJECT_NAME: My Project
-DEV_MODE: production
-GIT_COMMIT: {sh: git log -n 1 --format=%h}
-```
-
-#### Variables expansion
-
-Variables are expanded 2 times by default. You can change that by setting the
-`expansions:` option. Change that will be necessary if you compose many
-variables together:
-
-```yml
-version: '2'
-
-expansions: 3
-
-vars:
-  FOO: foo
-  BAR: bar
-  BAZ: baz
-  FOOBAR: "{{.FOO}}{{.BAR}}"
-  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
-
-tasks:
-  default:
-    cmds:
-      - echo "{{.FOOBARBAZ}}"
-```
-
-#### Dynamic variables
-
-The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
-The value will be treated as a command and the output assigned. If there is one
-or more trailing newlines, the last newline will be trimmed.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
-    vars:
-      GIT_COMMIT:
-        sh: git log -n 1 --format=%h
-```
-
-This works for all types of variables.
-
-### Go's template engine
-
-Task parse commands as [Go's template engine][gotemplate] before executing
-them. Variables are accessible through dot syntax (`.VARNAME`).
-
-All functions by the Go's [sprig lib](http://masterminds.github.io/sprig/)
-are available. The following example gets the current date in a given format:
-
-```yml
-version: '2'
-
-tasks:
-  print-date:
-    cmds:
-      - echo {{now | date "2006-01-02"}}
-```
-
-Task also adds the following functions:
-
-- `OS`: Returns operating system. Possible values are "windows", "linux",
-  "darwin" (macOS) and "freebsd".
-- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
-  or "s390x".
-- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
-- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.

-### Help
-
-Running `task --list` (or `task -l`) lists all tasks with a description.
-The following taskfile:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    desc: Build the go binary.
-    cmds:
-      - go build -v -i main.go
-
-  test:
-    desc: Run all the go tests.
-    cmds:
-      - go test -race ./...
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-would print the following output:
-
-```bash
-* build:   Build the go binary.
-* test:    Run all the go tests.
-```
-
-## Silent mode
-
-Silent mode disables echoing of commands before Task runs it.
-For the following Taskfile:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-```
-
-Normally this will be print:
-
-```sh
-echo "Print something"
-Print something
-```
-
-With silent mode on, the below will be print instead:
-
-```sh
-Print something
-```
-
-There's three ways to enable silent mode:
-
-* At command level:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: echo "Print something"
-        silent: true
-```
-
-* At task level:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-    silent: true
-```
-
-* Or globally with `--silent` or `-s` flag
-
-If you want to suppress stdout instead, just redirect a command to `/dev/null`:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "This will print nothing" > /dev/null
-```
-
-## Watch tasks (experimental)
-
-If you give a `--watch` or `-w` argument, task will watch for files changes
-and run the task again. This requires the `sources` attribute to be given,
-so task know which files to watch.
-
-## Examples
-
-The [go-task/examples][examples] intends to be a collection of Taskfiles for
-various use cases.
-(It still lacks many examples, though. Contributions are welcome).

+# Task
+
+Task is a task runner / build tool that aims to be simpler and easier to use
+than, for example, [GNU Make][make].
+
+Since it's written in [Go][go], Task is just a single binary and has no other
+dependencies, which means you don't need to mess with any complicated install
+setups just to use a build tool.
+
+Once [installed](installation.md), you just need to describe your build tasks
+using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
+
+```yaml
+version: '2'
+
+tasks:
+  hello:
+    cmds:
+      - echo 'Hello World from Task!'
+    silent: true
+```
+
+And call it by running `task hello` from you terminal.
+
+The above example is just the start, you can take a look at the [usage](usage.md)
+guide to check the full schema documentation and Task features.
+
+## Features
+
+- [Easy installation](installation.md): just download a single binary, add to
+  $PATH and you're done! Or you can also install using [Homebrew][homebrew] or
+  [Snapcraft][snapcraft] if you want;
+- Available on CIs: by adding [this simple command](installation.md#install-script)
+  to install on your CI script and you're done to use Task as part of your CI pipeline;
+- Truly cross-platform: while most build tools only work well on Linux or macOS,
+  Task also supports Windows thanks to [this awesome shell interpreter for Go][sh];
+- Great for code generation: you can easily [prevent a task from running](usage.md#prevent-unnecessary-work)
+  if a given set of files haven't changed since last run (based either on its
+  timestamp or content).

+# Installation
+
+## Binary
+
+Or you can download the binary from the [releases][releases] page and add to
+your $PATH. DEB and RPM packages are also available.
+The `task_checksums.txt` file contains the sha256 checksum for each file.
+
+## Homebrew
+
+If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
+as simple as running:
+
+```bash
+brew install go-task/tap/go-task
+```
+
+## Snap
+
+Task is available for [Snapcraft][snapcraft], but keep in mind that your
+Linux distribution should allow classic confinement for Snaps to Task work
+right:
+
+```bash
+sudo snap install task
+```
+
+## Go
+
+Task now uses [Go Modules](https://github.com/golang/go/wiki/Modules), which
+means you may have trouble compiling it on older Go versions.
+
+For CI environments we recommend using the [Install Script](#install-script)
+instead, which is faster and more stable, since it'll just download the latest
+released binary, instead of compiling the edge (master branch) version.
+
+Installing in your `$GOPATH`:
+
+```bash
+go get -u -v github.com/go-task/task/cmd/task
+```
+
+Installing in another directory:
+
+```bash
+git clone https://github.com/go-task/task
+cd task
+
+# compiling binary to $GOPATH/bin
+go install -v
+
+# compiling it to another location
+# use -o ./task.exe on Windows
+go build -v -o ./task ./cmd/task
+```
+
+Both methods requires having the [Go][go] environment properly setup locally.
+
+## Install script
+
+We also have a [install script][installscript], which is very useful on
+scanarios like CIs. Many thanks to [godownloader][godownloader] for allowing
+easily generating this script.
+
+```bash
+curl -s https://taskfile.org/install.sh | sh
+```
+
+> This method will download the binary on the local `./bin` directory by default.

+# Usage
+
+## Getting started
+
+Create a file called `Taskfile.yml` in the root of your project.
+The `cmds` attribute should contain the commands of a task.
+The example below allows compiling a Go app and uses [Minify][minify] to concat
+and minify multiple CSS files into a single one.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+Running the tasks is as simple as running:
+
+```bash
+task assets build
+```
+
+Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
+interpreter. So you can write sh/bash commands and it will work even on
+Windows, where `sh` or `bash` are usually not available. Just remember any
+executable called must be available by the OS or in PATH.
+
+If you ommit a task name, "default" will be assumed.
+
+## Environment
+
+You can specify environment variables that are added when running a command:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo $hallo
+    env:
+      hallo: welt
+```
+
+## Operating System specific tasks
+
+If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your Taskfile
+based on the operating system.
+
+Example:
+
+Taskfile.yml:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo "default"
+```
+
+Taskfile_linux.yml:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo "linux"
+```
+
+Will print out `linux` and not `default`.
+
+Keep in mind that the version of the files should match. Also, when redefining
+a task the whole task is replaced, properties of the task are not merged.
+
+It's also possible to have an OS specific `Taskvars.yml` file, like
+`Taskvars_windows.yml`, `Taskfile_linux.yml`, or `Taskvars_darwin.yml`. See the
+[variables section](#variables) below.
+
+## Including other Taskfiles
+
+> This feature is still experimental and may have bugs.
+
+If you want to share tasks between different projects (Taskfiles), you can use
+the importing mechanism to include other Taskfiles using the `includes` keyword:
+
+```yaml
+version: '2'
+
+includes:
+  docs: ./documentation # will look for ./documentation/Taskfile.yml
+  docker: ./DockerTasks.yml
+```
+
+The tasks described in the given Taskfiles will be available with the informed
+namespace. So, you'd call `task docs:serve` to run the `serve` task from
+`documentation/Taskfile.yml` or `task docker:build` to run the `build` task
+from the `DockerTasks.yml` file.
+
+> The included Taskfiles must be using the same schema version the main
+> Taskfile uses.
+
+> Also, for now included Taskfiles can't include other Taskfiles.
+> This was a deliberate decision to keep use and implementation simple.
+> If you disagree, open an GitHub issue and explain your use case. =)
+
+## Task directory
+
+By default, tasks will be executed in the directory where the Taskfile is
+located. But you can easily make the task run in another folder informing
+`dir`:
+
+```yaml
+version: '2'
+
+tasks:
+  serve:
+    dir: public/www
+    cmds:
+      # run http server
+      - caddy
+```
+
+## Task dependencies
+
+You may have tasks that depend on others. Just pointing them on `deps` will
+make them run automatically before running the parent task:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    deps: [assets]
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+In the above example, `assets` will always run right before `build` if you run
+`task build`.
+
+A task can have only dependencies and no commands to group tasks together:
+
+```yaml
+version: '2'
+
+tasks:
+  assets:
+    deps: [js, css]
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+If there is more than one dependency, they always run in parallel for better
+performance.
+
+If you want to pass information to dependencies, you can do that the same
+manner as you would to [call another task](#calling-another-task):
+
+```yaml
+version: '2'
+
+tasks:
+  default:
+    deps:
+      - task: echo_sth
+        vars: {TEXT: "before 1"}
+      - task: echo_sth
+        vars: {TEXT: "before 2"}
+    cmds:
+      - echo "after"
+
+  echo_sth:
+    cmds:
+      - echo {{.TEXT}}
+```
+
+## Calling another task
+
+When a task has many dependencies, they are executed concurrently. This will
+often result in a faster build pipeline. But in some situations you may need
+to call other tasks serially. In this case, just use the following syntax:
+
+```yaml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: task-to-be-called
+      - task: another-task
+      - echo "Both done"
+
+  task-to-be-called:
+    cmds:
+      - echo "Task to be called"
+
+  another-task:
+    cmds:
+      - echo "Another task"
+```
+
+Overriding variables in the called task is as simple as informing `vars`
+attribute:
+
+```yaml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: write-file
+        vars: {FILE: "hello.txt", CONTENT: "Hello!"}
+      - task: write-file
+        vars: {FILE: "world.txt", CONTENT: "World!"}
+
+  write-file:
+    cmds:
+      - echo "{{.CONTENT}}" > {{.FILE}}
+```
+
+The above syntax is also supported in `deps`.
+
+## Prevent unnecessary work
+
+If a task generates something, you can inform Task the source and generated
+files, so Task will prevent to run them if not necessary.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    deps: [js, css]
+    cmds:
+      - go build -v -i main.go
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+    sources:
+      - src/js/**/*.js
+    generates:
+      - public/script.js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+    sources:
+      - src/css/**/*.css
+    generates:
+      - public/style.css
+```
+
+`sources` and `generates` can be files or file patterns. When both are given,
+Task will compare the modification date/time of the files to determine if it's
+necessary to run the task. If not, it will just print a message like
+`Task "js" is up to date`.
+
+If you prefer this check to be made by the content of the files, instead of
+its timestamp, just set the `method` property to `checksum`.
+You will probably want to ignore the `.task` folder in your `.gitignore` file
+(It's there that Task stores the last checksum).
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build .
+    sources:
+      - ./*.go
+    generates:
+      - app{{exeExt}}
+    method: checksum
+```
+
+> TIP: method `none` skips any validation and always run the task.
+
+Alternatively, you can inform a sequence of tests as `status`. If no error
+is returned (exit status 0), the task is considered up-to-date:
+
+```yaml
+version: '2'
+
+tasks:
+  generate-files:
+    cmds:
+      - mkdir directory
+      - touch directory/file1.txt
+      - touch directory/file2.txt
+    # test existence of files
+    status:
+      - test -d directory
+      - test -f directory/file1.txt
+      - test -f directory/file2.txt
+```
+
+You can use `--force` or `-f` if you want to force a task to run even when
+up-to-date.
+
+Also, `task --status [tasks]...` will exit with a non-zero exit code if any of
+the tasks are not up-to-date.
+
+## Variables
+
+When doing interpolation of variables, Task will look for the below.
+They are listed below in order of importance (e.g. most important first):
+
+- Variables declared locally in the task
+- Variables given while calling a task from another.
+  (See [Calling another task](#calling-another-task) above)
+- Variables declared in the `vars:` option in the `Taskfile`
+- Variables available in the `Taskvars.yml` file
+- Environment variables
+
+Example of sending parameters with environment variables:
+
+```bash
+$ TASK_VARIABLE=a-value task do-something
+```
+
+Since some shells don't support above syntax to set environment variables
+(Windows) tasks also accepts a similar style when not in the beginning of
+the command. Variables given in this form are only visible to the task called
+right before.
+
+```bash
+$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
+```
+
+Example of locally declared vars:
+
+```yaml
+version: '2'
+
+tasks:
+  print-var:
+    cmds:
+      echo "{{.VAR}}"
+    vars:
+      VAR: Hello!
+```
+
+Example of global vars in a `Taskfile.yml`:
+
+```yaml
+version: '2'
+
+vars:
+  GREETING: Hello from Taskfile!
+
+tasks:
+  greet:
+    cmds:
+      - echo "{{.GREETING}}"
+```
+
+Example of `Taskvars.yml` file:
+
+```yaml
+PROJECT_NAME: My Project
+DEV_MODE: production
+GIT_COMMIT: {sh: git log -n 1 --format=%h}
+```
+
+### Variables expansion
+
+Variables are expanded 2 times by default. You can change that by setting the
+`expansions:` option. Change that will be necessary if you compose many
+variables together:
+
+```yaml
+version: '2'
+
+expansions: 3
+
+vars:
+  FOO: foo
+  BAR: bar
+  BAZ: baz
+  FOOBAR: "{{.FOO}}{{.BAR}}"
+  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
+
+tasks:
+  default:
+    cmds:
+      - echo "{{.FOOBARBAZ}}"
+```
+
+### Dynamic variables
+
+The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
+The value will be treated as a command and the output assigned. If there is one
+or more trailing newlines, the last newline will be trimmed.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
+    vars:
+      GIT_COMMIT:
+        sh: git log -n 1 --format=%h
+```
+
+This works for all types of variables.
+
+## Go's template engine
+
+Task parse commands as [Go's template engine][gotemplate] before executing
+them. Variables are accessible through dot syntax (`.VARNAME`).
+
+All functions by the Go's [sprig lib](http://masterminds.github.io/sprig/)
+are available. The following example gets the current date in a given format:
+
+```yaml
+version: '2'
+
+tasks:
+  print-date:
+    cmds:
+      - echo {{now | date "2006-01-02"}}
+```
+
+Task also adds the following functions:
+
+- `OS`: Returns operating system. Possible values are "windows", "linux",
+  "darwin" (macOS) and "freebsd".
+- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
+  or "s390x".
+- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
+- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.
+- `toSlash`: Does nothing on Unix, but on Windows converts a string from `\`
+  path format to `/`.
+- `fromSlash`: Oposite of `toSlash`. Does nothing on Unix, but on Windows
+  converts a string from `\` path format to `/`.
+- `exeExt`: Returns the right executable extension for the current OS
+  (`".exe"` for Windows, `""` for others).
+
+Example:
+
+```yaml
+version: '2'
+
+tasks:
+  print-os:
+    cmds:
+      - echo '{{OS}} {{ARCH}}'
+      - echo '{{if eq OS "windows"}}windows-command{{else}}unix-command{{end}}'
+      # This will be path/to/file on Unix but path\to\file on Windows
+      - echo '{{fromSlash "path/to/file"}}'
+  enumerated-file:
+    vars:
+      CONTENT: |
+        foo
+        bar
+    cmds:
+      - |
+        cat << EOF > output.txt
+        {{range $i, $line := .CONTENT | splitLines -}}
+        {{printf "%3d" $i}}: {{$line}}
+        {{end}}EOF
+```
+
+## Help
+
+Running `task --list` (or `task -l`) lists all tasks with a description.
+The following taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    desc: Build the go binary.
+    cmds:
+      - go build -v -i main.go
+
+  test:
+    desc: Run all the go tests.
+    cmds:
+      - go test -race ./...
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+would print the following output:
+
+```bash
+* build:   Build the go binary.
+* test:    Run all the go tests.
+```
+
+## Silent mode
+
+Silent mode disables echoing of commands before Task runs it.
+For the following Taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+```
+
+Normally this will be print:
+
+```sh
+echo "Print something"
+Print something
+```
+
+With silent mode on, the below will be print instead:
+
+```sh
+Print something
+```
+
+There's three ways to enable silent mode:
+
+* At command level:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: echo "Print something"
+        silent: true
+```
+
+* At task level:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+    silent: true
+```
+
+* Or globally with `--silent` or `-s` flag
+
+If you want to suppress stdout instead, just redirect a command to `/dev/null`:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "This will print nothing" > /dev/null
+```
+
+## Dry run mode
+
+Dry run mode (`--dry`) compiles and steps through each task, printing the commands
+that would be run without executing them. This is useful for debugging your Taskfiles.
+
+## Ignore errors
+
+You have the option to ignore errors during command execution.
+Given the following Taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - exit 1
+      - echo "Hello World"
+```
+
+Task will abort the execution after running `exit 1` because the status code `1` stands for `EXIT_FAILURE`.
+However it is possible to continue with execution using `ignore_error`:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: exit 1
+        ignore_error: true
+      - echo "Hello World"
+```
+
+`ignore_error` can also be set for a task, which mean errors will be supressed
+for all commands. But keep in mind this option won't propagate to other tasks
+called either by `deps` or `cmds`!
+
+## Output syntax
+
+By default, Task just redirect the STDOUT and STDERR of the running commands
+to the shell in real time. This is good for having live feedback for log
+printed by commands, but the output can become messy if you have multiple
+commands running at the same time and printing lots of stuff.
+
+To make this more customizable, there are currently three different output
+options you can choose:
+
+- `interleaved` (default)
+- `group`
+- `prefixed`
+
+To choose another one, just set it to root in the Taskfile:
+
+```yaml
+version: '2'
+
+output: 'group'
+
+tasks:
+  # ...
+```
+
+ The `group` output will print the entire output of a command once, after it
+ finishes, so you won't have live feedback for commands that take a long time
+ to run.
+
+ The `prefix` output will prefix every line printed by a command with
+ `[task-name] ` as the prefix, but you can customize the prefix for a command
+ with the `prefix:` attribute:
+
+ ```yaml
+version: '2'
+
+output: prefixed
+
+tasks:
+  default:
+    deps:
+      - task: print
+        vars: {TEXT: foo}
+      - task: print
+        vars: {TEXT: bar}
+      - task: print
+        vars: {TEXT: baz}
+
+  print:
+    cmds:
+      - echo "{{.TEXT}}"
+    prefix: "print-{{.TEXT}}"
+    silent: true
+```
+
+```bash
+$ task default
+[print-foo] foo
+[print-bar] bar
+[print-baz] baz
+```
+
+## Watch tasks
+
+If you give a `--watch` or `-w` argument, task will watch for file changes
+and run the task again. This requires the `sources` attribute to be given,
+so task know which files to watch.

+# SemVer
+
+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix
+
+[![Stability:
+Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
+[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
+
+## Parsing Semantic Versions
+
+To parse a semantic version use the `NewVersion` function. For example,
+
+```go
+    v, err := semver.NewVersion("1.2.3-beta.1+build345")
+```
+
+If there is an error the version wasn't parseable. The version object has methods
+to get the parts of the version, compare it to other versions, convert the
+version back into a string, and get the original string. For more details
+please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
+package from the standard library. For example,
+
+```go
+    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+    vs := make([]*semver.Version, len(raw))
+	for i, r := range raw {
+		v, err := semver.NewVersion(r)
+		if err != nil {
+			t.Errorf("Error parsing version: %s", err)
+		}
+
+		vs[i] = v
+	}
+
+	sort.Sort(semver.Collection(vs))
+```
+
+## Checking Version Constraints
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+    c, err := semver.NewConstraint(">= 1.2.3")
+    if err != nil {
+        // Handle constraint not being parseable.
+    }
+
+    v, _ := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parseable.
+    }
+    // Check if the version meets the constraints. The a variable will be true.
+    a := c.Check(v)
+```
+
+## Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma separated and comparisons. These are then separated by || separated or
+comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+* `=`: equal (aliased to no operator)
+* `!=`: not equal
+* `>`: greater than
+* `<`: less than
+* `>=`: greater than or equal to
+* `<=`: less than or equal to
+
+_Note, according to the Semantic Version specification pre-releases may not be
+API compliant with their release counterpart. It says,_
+
+> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._
+
+_SemVer comparisons without a pre-release value will skip pre-release versions.
+For example, `>1.2.3` will skip pre-releases when looking at a list of values
+while `>1.2.3-alpha.1` will evaluate pre-releases._
+
+## Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
+
+## Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the pack level comparison (see tilde below). For example,
+
+* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `>= 1.2.x` is equivalent to `>= 1.2.0`
+* `<= 2.x` is equivalent to `<= 3`
+* `*` is equivalent to `>= 0.0.0`
+
+## Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+* `~1` is equivalent to `>= 1, < 2`
+* `~2.3` is equivalent to `>= 2.3, < 2.4`
+* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `~1.x` is equivalent to `>= 1, < 2`
+
+## Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes. This is useful
+when comparisons of API versions as a major change is API breaking. For example,
+
+* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+* `^2.3` is equivalent to `>= 2.3, < 3`
+* `^2.x` is equivalent to `>= 2.0.0, < 3`
+
+# Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+    if err != nil {
+        // Handle constraint not being parseable.
+    }
+
+    v, _ := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parseable.
+    }
+
+    // Validate a version against a constraint.
+    a, msgs := c.Validate(v)
+    // a is false
+    for _, m := range msgs {
+        fmt.Println(m)
+
+        // Loops over the errors which would read
+        // "1.3 is greater than 1.2.3"
+        // "1.3 is less than 1.4"
+    }
+```

+# Sprig: Template functions for Go templates
+[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
+[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
+
+The Go language comes with a [built-in template
+language](http://golang.org/pkg/text/template/), but not
+very many template functions. This library provides a group of commonly
+used template functions.
+
+It is inspired by the template functions found in
+[Twig](http://twig.sensiolabs.org/documentation) and also in various
+JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
+
+## Usage
+
+Template developers can read the [Sprig function documentation](http://masterminds.github.io/sprig/) to
+learn about the >100 template functions available.
+
+For Go developers wishing to include Sprig as a library in their programs,
+API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig), but
+read on for standard usage.
+
+### Load the Sprig library
+
+To load the Sprig `FuncMap`:
+
+```go
+
+import (
+  "github.com/Masterminds/sprig"
+  "html/template"
+)
+
+// This example illustrates that the FuncMap *must* be set before the
+// templates themselves are loaded.
+tpl := template.Must(
+  template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
+)
+
+
+```
+
+### Call the functions inside of templates
+
+By convention, all functions are lowercase. This seems to follow the Go
+idiom for template functions (as opposed to template methods, which are
+TitleCase).
+
+
+Example:
+
+```
+{{ "hello!" | upper | repeat 5 }}
+```
+
+Produces:
+
+```
+HELLO!HELLO!HELLO!HELLO!HELLO!
+```
+
+## Principles:
+
+The following principles were used in deciding on which functions to add, and
+determining how to implement them.
+
+- Template functions should be used to build layout. Therefore, the following
+  types of operations are within the domain of template functions:
+  - Formatting
+  - Layout
+  - Simple type conversions
+  - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
+- Template functions should not return errors unless there is no way to print
+  a sensible value. For example, converting a string to an integer should not
+  produce an error if conversion fails. Instead, it should display a default
+  value that can be displayed.
+- Simple math is necessary for grid layouts, pagers, and so on. Complex math
+  (anything other than arithmetic) should be done outside of templates.
+- Template functions only deal with the data passed into them. They never retrieve
+  data from a source.
+- Finally, do not override core Go template functions.

-Date Functions
-
-	- date FORMAT TIME: Format a date, where a date is an integer type or a time.Time type, and
-	  format is a time.Format formatting string.
-	- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
-	  parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
-	- now: Current time.Time, for feeding into date-related functions.
-	- htmlDate TIME: Format a date for use in the value field of an HTML "date" form element.
-	- dateInZone FORMAT TIME TZ: Like date, but takes three arguments: format, timestamp,
-	  timezone.
-	- htmlDateInZone TIME TZ: Like htmlDate, but takes two arguments: timestamp,
-	  timezone.
-
-String Functions
-
-	- abbrev: Truncate a string with ellipses. `abbrev 5 "hello world"` yields "he..."
-	- abbrevboth: Abbreviate from both sides, yielding "...lo wo..."
-	- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
-	- trim: strings.TrimSpace
-	- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
-	- trimSuffix: strings.TrimSuffix, but with the argument order reversed: `trimSuffix "-" "ends-with-"`
-	- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
-	- upper: strings.ToUpper
-	- lower: strings.ToLower
-	- nospace: Remove all space characters from a string. `nospace "h e l l o"` becomes "hello"
-	- title: strings.Title
-	- untitle: Remove title casing
-	- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
-	- substr: Given string, start, and length, return a substr.
-	- initials: Given a multi-word string, return the initials. `initials "Matt Butcher"` returns "MB"
-	- randAlphaNum: Given a length, generate a random alphanumeric sequence
-	- randAlpha: Given a length, generate an alphabetic string
-	- randAscii: Given a length, generate a random ASCII string (symbols included)
-	- randNumeric: Given a length, generate a string of digits.
-	- swapcase: SwapCase swaps the case of a string using a word based algorithm. see https://godoc.org/github.com/Masterminds/goutils#SwapCase
-	- shuffle: Shuffle randomizes runes in a string and returns the result. It uses default random source in `math/rand`
-	- snakecase: convert all upper case characters in a string to underscore format.
-	- camelcase: convert all lower case characters behind underscores to upper case character
-	- wrap: Force a line wrap at the given width. `wrap 80 "imagine a longer string"`
-	- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, "<br>", $html`
-	- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)
-	- hasPrefix: strings.hasPrefix, but with the arguments switched
-	- hasSuffix: strings.hasSuffix, but with the arguments switched
-	- quote: Wrap string(s) in double quotation marks, escape the contents by adding '\' before '"'.
-	- squote: Wrap string(s) in double quotation marks, does not escape content.
-	- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
-	- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces "    foo\n    bar"
-	- nindent: Indent a string using space characters and prepend a new line. `indent 4 "foo\nbar"` produces "\n    foo\n    bar"
-	- replace: Replace an old with a new in a string: `$name | replace " " "-"`
-	- plural: Choose singular or plural based on length: `len $fish | plural "one anchovy" "many anchovies"`
-	- sha256sum: Generate a hex encoded sha256 hash of the input
-	- toString: Convert something to a string
-
-String Slice Functions:
-
-	- join: strings.Join, but as `join SEP SLICE`
-	- split: strings.Split, but as `split SEP STRING`. The results are returned
-	  as a map with the indexes set to _N, where N is an integer starting from 0.
-	  Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
-	- splitList: strings.Split, but as `split SEP STRING`. The results are returned
-	  as an array.
-	- toStrings: convert a list to a list of strings. 'list 1 2 3 | toStrings' produces '["1" "2" "3"]'
-	- sortAlpha: sort a list lexicographically.
-
-Integer Slice Functions:
-
-	- until: Given an integer, returns a slice of counting integers from 0 to one
-	  less than the given integer: `range $i, $e := until 5`
-	- untilStep: Given start, stop, and step, return an integer slice starting at
-	  'start', stopping at `stop`, and incrementing by 'step. This is the same
-	  as Python's long-form of 'range'.
-
-Conversions:
-
-	- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
-	- int64: Convert a string or another numeric type to an int64.
-	- int: Convert a string or another numeric type to an int.
-	- float64: Convert a string or another numeric type to a float64.
-
-Defaults:
-
-	- default: Give a default value. Used like this: trim "   "| default "empty".
-	  Since trim produces an empty string, the default value is returned. For
-	  things with a length (strings, slices, maps), len(0) will trigger the default.
-	  For numbers, the value 0 will trigger the default. For booleans, false will
-	  trigger the default. For structs, the default is never returned (there is
-	  no clear empty condition). For everything else, nil value triggers a default.
-	- empty: Return true if the given value is the zero value for its type.
-	  Caveats: structs are always non-empty. This should match the behavior of
-	  {{if pipeline}}, but can be used inside of a pipeline.
-	- coalesce: Given a list of items, return the first non-empty one.
-	  This follows the same rules as 'empty'. '{{ coalesce .someVal 0 "hello" }}`
-	  will return `.someVal` if set, or else return "hello". The 0 is skipped
-	  because it is an empty value.
-	- compact: Return a copy of a list with all of the empty values removed.
-	  'list 0 1 2 "" | compact' will return '[1 2]'
-
-OS:
-	- env: Resolve an environment variable
-	- expandenv: Expand a string through the environment
-
-File Paths:
-	- base: Return the last element of a path. https://golang.org/pkg/path#Base
-	- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
-	- clean: Clean a path to the shortest equivalent name.  (e.g. remove "foo/.."
-	  from "foo/../bar.html") https://golang.org/pkg/path#Clean
-	- ext: https://golang.org/pkg/path#Ext
-	- isAbs: https://golang.org/pkg/path#IsAbs
-
-Encoding:
-	- b64enc: Base 64 encode a string.
-	- b64dec: Base 64 decode a string.
-
-Reflection:
-
-	- typeOf: Takes an interface and returns a string representation of the type.
-	  For pointers, this will return a type prefixed with an asterisk(`*`). So
-	  a pointer to type `Foo` will be `*Foo`.
-	- typeIs: Compares an interface with a string name, and returns true if they match.
-	  Note that a pointer will not match a reference. For example `*Foo` will not
-	  match `Foo`.
-	- typeIsLike: Compares an interface with a string name and returns true if
-	  the interface is that `name` or that `*name`. In other words, if the given
-	  value matches the given type or is a pointer to the given type, this returns
-	  true.
-	- kindOf: Takes an interface and returns a string representation of its kind.
-	- kindIs: Returns true if the given string matches the kind of the given interface.
-
-	Note: None of these can test whether or not something implements a given
-	interface, since doing so would require compiling the interface in ahead of
-	time.
-
-Data Structures:
-
-	- tuple: Takes an arbitrary list of items and returns a slice of items. Its
-	  tuple-ish properties are mainly gained through the template idiom, and not
-	  through an API provided here. WARNING: The implementation of tuple will
-	  change in the future.
-	- list: An arbitrary ordered list of items. (This is prefered over tuple.)
-	- dict: Takes a list of name/values and returns a map[string]interface{}.
-	  The first parameter is converted to a string and stored as a key, the
-	  second parameter is treated as the value. And so on, with odds as keys and
-	  evens as values. If the function call ends with an odd, the last key will
-	  be assigned the empty string. Non-string keys are converted to strings as
-	  follows: []byte are converted, fmt.Stringers will have String() called.
-	  errors will have Error() called. All others will be passed through
-	  fmt.Sprtinf("%v").
-
-Lists Functions:
-
-These are used to manipulate lists: '{{ list 1 2 3 | reverse | first }}'
-
-	- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
-	- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
-	- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
-	- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
-	- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
-	- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
-	- reverse: Reverse the items in a list.
-	- uniq: Remove duplicates from a list.
-	- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
-	- has: Return 'true' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
-
-Dict Functions:
-
-These are used to manipulate dicts.
-
-	- set: Takes a dict, a key, and a value, and sets that key/value pair in
-	  the dict. `set $dict $key $value`. For convenience, it returns the dict,
-	  even though the dict was modified in place.
-	- unset: Takes a dict and a key, and deletes that key/value pair from the
-	  dict. `unset $dict $key`. This returns the dict for convenience.
-	- hasKey: Takes a dict and a key, and returns boolean true if the key is in
-	  the dict.
-	- pluck: Given a key and one or more maps, get all of the values for that key.
-	- keys: Get an array of all of the keys in a dict.
-	- pick: Select just the given keys out of the dict, and return a new dict.
-	- omit: Return a dict without the given keys.
-
-Math Functions:
-
-Integer functions will convert integers of any width to `int64`. If a
-string is passed in, functions will attempt to convert with
-`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
-
-	- add1: Increment an integer by 1
-	- add: Sum an arbitrary number of integers
-	- sub: Subtract the second integer from the first
-	- div: Divide the first integer by the second
-	- mod: Module of first integer divided by second
-	- mul: Multiply integers
-	- max: Return the biggest of a series of one or more integers
-	- min: Return the smallest of a series of one or more integers
-	- biggest: DEPRECATED. Return the biggest of a series of one or more integers
-
-Crypto Functions:
-
-	- genPrivateKey: Generate a private key for the given cryptosystem. If no
-	  argument is supplied, by default it will generate a private key using
-	  the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.
-	- derivePassword: Derive a password from the given parameters according to the ["Master Password" algorithm](http://masterpasswordapp.com/algorithm.html)
-	  Given parameters (in order) are:
-          `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
-           `user`, and `site`
-
-SemVer Functions:
-
-These functions provide version parsing and comparisons for SemVer 2 version
-strings.
-
-	- semver: Parse a semantic version and return a Version object.
-	- semverCompare: Compare a SemVer range to a particular version.
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.
