 # Changelog
 
+## v3.22.0 - 2023-03-10
+
+- Add a brand new `--global` (`-g`) flag that will run a Taskfile from your
+  `$HOME` directory. This is useful to have automation that you can run from
+  anywhere in your system!
+  ([Documentation](https://taskfile.dev/usage/#running-a-global-taskfile), [#1029](https://github.com/go-task/task/pull/1029) by @andreynering).
+- Add ability to set `error_only: true` on the `group` output mode. This will
+  instruct Task to only print a command output if it returned with a non-zero
+  exit code
+  ([#664](https://github.com/go-task/task/issues/664), [#1022](https://github.com/go-task/task/pull/1022) by @jaedle).
+- Fixed bug where `.task/checksum` file was sometimes not being created when
+  task also declares a `status:`
+  ([#840](https://github.com/go-task/task/issues/840), [#1035](https://github.com/go-task/task/pull/1035) by @harelwa, [#1037](https://github.com/go-task/task/pull/1037) by @pd93).
+- Refactored and decoupled fingerprinting from the main Task executor ([#1039](https://github.com/go-task/task/issues/1039) by @pd93).
+- Fixed deadlock issue when using `run: once`
+  ([#715](https://github.com/go-task/task/issues/715), [#1025](https://github.com/go-task/task/pull/1025) by @theunrepentantgeek).
+
+## v3.21.0 - 2023-02-22
+
+- Added new `TASK_VERSION` special variable
+  ([#990](https://github.com/go-task/task/issues/990), [#1014](https://github.com/go-task/task/pull/1014) by @ja1code).
+- Fixed a bug where tasks were sometimes incorrectly marked as internal ([#1007](https://github.com/go-task/task/pull/1007) by @pd93).
+- Update to Go 1.20 (bump minimum version to 1.19) ([#1010](https://github.com/go-task/task/pull/1010) by @pd93)
+- Added environment variable `FORCE_COLOR` support to force color output. Usefull for environments without TTY ([#1003](https://github.com/go-task/task/pull/1003) by @automation-stack)
+
+## v3.20.0 - 2023-01-14
+
+- Improve behavior and performance of status checking when using the
+  `timestamp` mode
+  ([#976](https://github.com/go-task/task/issues/976), [#977](https://github.com/go-task/task/pull/977) by @aminya).
+- Performance optimizations were made for large Taskfiles
+  ([#982](https://github.com/go-task/task/pull/982) by @pd93).
+- Add ability to configure options for the [`set`](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html)
+  and [`shopt`](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html) builtins
+  ([#908](https://github.com/go-task/task/issues/908), [#929](https://github.com/go-task/task/pull/929) by @pd93, [Documentation](http://taskfile.dev/usage/#set-and-shopt)).
+- Add new `platforms:` attribute to `task` and `cmd`, so it's now possible to
+  choose in which platforms that given task or command will be run on. Possible
+  values are operating system (GOOS), architecture (GOARCH) or a combination of
+  the two. Example: `platforms: [linux]`, `platforms: [amd64]` or
+  `platforms: [linux/amd64]`. Other platforms will be skipped
+  ([#978](https://github.com/go-task/task/issues/978), [#980](https://github.com/go-task/task/pull/980) by @leaanthony).
+
+## v3.19.1 - 2022-12-31
+
+- Small bug fix: closing `Taskfile.yml` once we're done reading it
+  ([#963](https://github.com/go-task/task/issues/963), [#964](https://github.com/go-task/task/pull/964) by @HeCorr).
+- Fixes a bug in v2 that caused a panic when using a `Taskfile_{{OS}}.yml` file
+  ([#961](https://github.com/go-task/task/issues/961), [#971](https://github.com/go-task/task/pull/971) by @pd93).
+- Fixed a bug where watch intervals set in the Taskfile were not being respected ([#969](https://github.com/go-task/task/pull/969), [#970](https://github.com/go-task/task/pull/970) by @pd93)
+- Add `--json` flag (alias `-j`) with the intent to improve support for code
+  editors and add room to other possible integrations. This is basic for now,
+  but we plan to add more info in the near future
+  ([#936](https://github.com/go-task/task/pull/936) by @davidalpert, [#764](https://github.com/go-task/task/issues/764)).
+
+## v3.19.0 - 2022-12-05
+
+- Installation via npm now supports [pnpm](https://pnpm.io/) as well
+  ([go-task/go-npm#2](https://github.com/go-task/go-npm/issues/2), [go-task/go-npm#3](https://github.com/go-task/go-npm/pull/3)).
+- It's now possible to run Taskfiles from subdirectories! A new `USER_WORKING_DIR` special
+  variable was added to add even more flexibility for monorepos
+  ([#289](https://github.com/go-task/task/issues/289), [#920](https://github.com/go-task/task/pull/920)).
+- Add task-level `dotenv` support
+  ([#389](https://github.com/go-task/task/issues/389), [#904](https://github.com/go-task/task/pull/904)).
+- It's now possible to use global level variables on `includes`
+  ([#942](https://github.com/go-task/task/issues/942), [#943](https://github.com/go-task/task/pull/943)).
+- The website got a brand new [translation to Chinese](https://task-zh.readthedocs.io/zh_CN/latest/)
+  by [@DeronW](https://github.com/DeronW). Thanks!
+
+## v3.18.0 - 2022-11-12
+
+- Show aliases on `task --list --silent` (`task --ls`). This means that aliases
+  will be completed by the completion scripts
+  ([#919](https://github.com/go-task/task/pull/919)).
+- Tasks in the root Taskfile will now be displayed first in `--list`/`--list-all`
+  output ([#806](https://github.com/go-task/task/pull/806), [#890](https://github.com/go-task/task/pull/890)).
+- It's now possible to call a `default` task in an included Taskfile by using
+  just the namespace. For example: `docs:default` is now automatically
+  aliased to `docs`
+  ([#661](https://github.com/go-task/task/issues/661), [#815](https://github.com/go-task/task/pull/815)).
+
+## v3.17.0 - 2022-10-14
+
+- Add a "Did you mean ...?" suggestion when a task does not exits another one
+  with a similar name is found
+  ([#867](https://github.com/go-task/task/issues/867), [#880](https://github.com/go-task/task/pull/880)).
+- Now YAML parse errors will print which Taskfile failed to parse
+  ([#885](https://github.com/go-task/task/issues/885), [#887](https://github.com/go-task/task/pull/887)).
+- Add ability to set `aliases` for tasks and namespaces ([#268](https://github.com/go-task/task/pull/268), [#340](https://github.com/go-task/task/pull/340), [#879](https://github.com/go-task/task/pull/879)).
+- Improvements to Fish shell completion
+  ([#897](https://github.com/go-task/task/pull/897)).
+- Added ability to set a different watch interval by setting
+  `interval: '500ms'` or using the `--interval=500ms` flag
+  ([#813](https://github.com/go-task/task/issues/813), [#865](https://github.com/go-task/task/pull/865)).
+- Add colored output to `--list`, `--list-all` and `--summary` flags ([#845](https://github.com/go-task/task/pull/845), [#874](https://github.com/go-task/task/pull/874)).
+- Fix unexpected behavior where `label:` was being shown instead of the task
+  name on `--list`
+  ([#603](https://github.com/go-task/task/issues/603), [#877](https://github.com/go-task/task/pull/877)).
+
+## v3.16.0 - 2022-09-29
+
+- Add `npm` as new installation method: `npm i -g @go-task/cli`
+  ([#870](https://github.com/go-task/task/issues/870), [#871](https://github.com/go-task/task/pull/871), [npm package](https://www.npmjs.com/package/@go-task/cli)).
+- Add support to marking tasks and includes as internal, which will hide them
+  from `--list` and `--list-all`
+  ([#818](https://github.com/go-task/task/pull/818)).
+
+## v3.15.2 - 2022-09-08
+
+- Fix error when using variable in `env:` introduced in the previous release
+  ([#858](https://github.com/go-task/task/issues/858), [#866](https://github.com/go-task/task/pull/866)).
+- Fix handling of `CLI_ARGS` (`--`) in Bash completion
+  ([#863](https://github.com/go-task/task/pull/863)).
+- On zsh completion, add ability to replace `--list-all` with `--list` as
+  already possible on the Bash completion
+  ([#861](https://github.com/go-task/task/pull/861)).
+
+## v3.15.0 - 2022-09-03
+
+- Add new special variables `ROOT_DIR` and `TASKFILE_DIR`. This was a highly
+  requested feature
+  ([#215](https://github.com/go-task/task/issues/215), [#857](https://github.com/go-task/task/pull/857), [Documentation](https://taskfile.dev/api/#special-variables)).
+- Follow symlinks on `sources`
+  ([#826](https://github.com/go-task/task/issues/826), [#831](https://github.com/go-task/task/pull/831)).
+- Improvements and fixes to Bash completion
+  ([#835](https://github.com/go-task/task/pull/835), [#844](https://github.com/go-task/task/pull/844)).
+
+## v3.14.1 - 2022-08-03
+
+- Always resolve relative include paths relative to the including Taskfile
+  ([#822](https://github.com/go-task/task/issues/822), [#823](https://github.com/go-task/task/pull/823)).
+- Fix ZSH and PowerShell completions to consider all tasks instead of just the
+  public ones (those with descriptions)
+  ([#803](https://github.com/go-task/task/pull/803)).
+
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the
+  `TASK_TEMP_DIR` environment variable.
+- Allow to override Task colors using environment variables:
+  `TASK_COLOR_RESET`, `TASK_COLOR_BLUE`, `TASK_COLOR_GREEN`,
+  `TASK_COLOR_CYAN`, `TASK_COLOR_YELLOW`, `TASK_COLOR_MAGENTA`
+  and `TASK_COLOR_RED`
+  ([#568](https://github.com/go-task/task/pull/568), [#792](https://github.com/go-task/task/pull/792)).
+- Fixed bug when using the `output: group` mode where STDOUT and STDERR were
+  being print in separated blocks instead of in the right order
+  ([#779](https://github.com/go-task/task/issues/779)).
+- Starting on this release, ARM architecture binaries are been released to Snap
+  as well
+  ([#795](https://github.com/go-task/task/issues/795)).
+- i386 binaries won't be available anymore on Snap because Ubuntu removed the support
+  for this architecture.
+- Upgrade mvdan.cc/sh, which fixes a bug with associative arrays
+  ([#785](https://github.com/go-task/task/issues/785), [mvdan/sh#884](https://github.com/mvdan/sh/issues/884), [mvdan/sh#893](https://github.com/mvdan/sh/pull/893)).
+
 ## v3.13.0 - 2022-06-13
 
 - Added `-n` as an alias to `--dry`
   ([#776](https://github.com/go-task/task/issues/776), [#777](https://github.com/go-task/task/pull/777)).
 - Fix behavior of interrupt (SIGINT, SIGTERM) signals. Task will now give time

 # Changelog
 
+## v3.22.0 - 2023-03-10
+
+- Add a brand new `--global` (`-g`) flag that will run a Taskfile from your
+  `$HOME` directory. This is useful to have automation that you can run from
+  anywhere in your system!
+  ([Documentation](https://taskfile.dev/usage/#running-a-global-taskfile), [#1029](https://github.com/go-task/task/pull/1029) by @andreynering).
+- Add ability to set `error_only: true` on the `group` output mode. This will
+  instruct Task to only print a command output if it returned with a non-zero
+  exit code
+  ([#664](https://github.com/go-task/task/issues/664), [#1022](https://github.com/go-task/task/pull/1022) by @jaedle).
+- Fixed bug where `.task/checksum` file was sometimes not being created when
+  task also declares a `status:`
+  ([#840](https://github.com/go-task/task/issues/840), [#1035](https://github.com/go-task/task/pull/1035) by @harelwa, [#1037](https://github.com/go-task/task/pull/1037) by @pd93).
+- Refactored and decoupled fingerprinting from the main Task executor ([#1039](https://github.com/go-task/task/issues/1039) by @pd93).
+- Fixed deadlock issue when using `run: once`
+  ([#715](https://github.com/go-task/task/issues/715), [#1025](https://github.com/go-task/task/pull/1025) by @theunrepentantgeek).
+
+## v3.21.0 - 2023-02-22
+
+- Added new `TASK_VERSION` special variable
+  ([#990](https://github.com/go-task/task/issues/990), [#1014](https://github.com/go-task/task/pull/1014) by @ja1code).
+- Fixed a bug where tasks were sometimes incorrectly marked as internal ([#1007](https://github.com/go-task/task/pull/1007) by @pd93).
+- Update to Go 1.20 (bump minimum version to 1.19) ([#1010](https://github.com/go-task/task/pull/1010) by @pd93)
+- Added environment variable `FORCE_COLOR` support to force color output. Usefull for environments without TTY ([#1003](https://github.com/go-task/task/pull/1003) by @automation-stack)
+
+## v3.20.0 - 2023-01-14
+
+- Improve behavior and performance of status checking when using the
+  `timestamp` mode
+  ([#976](https://github.com/go-task/task/issues/976), [#977](https://github.com/go-task/task/pull/977) by @aminya).
+- Performance optimizations were made for large Taskfiles
+  ([#982](https://github.com/go-task/task/pull/982) by @pd93).
+- Add ability to configure options for the [`set`](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html)
+  and [`shopt`](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html) builtins
+  ([#908](https://github.com/go-task/task/issues/908), [#929](https://github.com/go-task/task/pull/929) by @pd93, [Documentation](http://taskfile.dev/usage/#set-and-shopt)).
+- Add new `platforms:` attribute to `task` and `cmd`, so it's now possible to
+  choose in which platforms that given task or command will be run on. Possible
+  values are operating system (GOOS), architecture (GOARCH) or a combination of
+  the two. Example: `platforms: [linux]`, `platforms: [amd64]` or
+  `platforms: [linux/amd64]`. Other platforms will be skipped
+  ([#978](https://github.com/go-task/task/issues/978), [#980](https://github.com/go-task/task/pull/980) by @leaanthony).
+
+## v3.19.1 - 2022-12-31
+
+- Small bug fix: closing `Taskfile.yml` once we're done reading it
+  ([#963](https://github.com/go-task/task/issues/963), [#964](https://github.com/go-task/task/pull/964) by @HeCorr).
+- Fixes a bug in v2 that caused a panic when using a `Taskfile_{{OS}}.yml` file
+  ([#961](https://github.com/go-task/task/issues/961), [#971](https://github.com/go-task/task/pull/971) by @pd93).
+- Fixed a bug where watch intervals set in the Taskfile were not being respected ([#969](https://github.com/go-task/task/pull/969), [#970](https://github.com/go-task/task/pull/970) by @pd93)
+- Add `--json` flag (alias `-j`) with the intent to improve support for code
+  editors and add room to other possible integrations. This is basic for now,
+  but we plan to add more info in the near future
+  ([#936](https://github.com/go-task/task/pull/936) by @davidalpert, [#764](https://github.com/go-task/task/issues/764)).
+
+## v3.19.0 - 2022-12-05
+
+- Installation via npm now supports [pnpm](https://pnpm.io/) as well
+  ([go-task/go-npm#2](https://github.com/go-task/go-npm/issues/2), [go-task/go-npm#3](https://github.com/go-task/go-npm/pull/3)).
+- It's now possible to run Taskfiles from subdirectories! A new `USER_WORKING_DIR` special
+  variable was added to add even more flexibility for monorepos
+  ([#289](https://github.com/go-task/task/issues/289), [#920](https://github.com/go-task/task/pull/920)).
+- Add task-level `dotenv` support
+  ([#389](https://github.com/go-task/task/issues/389), [#904](https://github.com/go-task/task/pull/904)).
+- It's now possible to use global level variables on `includes`
+  ([#942](https://github.com/go-task/task/issues/942), [#943](https://github.com/go-task/task/pull/943)).
+- The website got a brand new [translation to Chinese](https://task-zh.readthedocs.io/zh_CN/latest/)
+  by [@DeronW](https://github.com/DeronW). Thanks!
+
+## v3.18.0 - 2022-11-12
+
+- Show aliases on `task --list --silent` (`task --ls`). This means that aliases
+  will be completed by the completion scripts
+  ([#919](https://github.com/go-task/task/pull/919)).
+- Tasks in the root Taskfile will now be displayed first in `--list`/`--list-all`
+  output ([#806](https://github.com/go-task/task/pull/806), [#890](https://github.com/go-task/task/pull/890)).
+- It's now possible to call a `default` task in an included Taskfile by using
+  just the namespace. For example: `docs:default` is now automatically
+  aliased to `docs`
+  ([#661](https://github.com/go-task/task/issues/661), [#815](https://github.com/go-task/task/pull/815)).
+
+## v3.17.0 - 2022-10-14
+
+- Add a "Did you mean ...?" suggestion when a task does not exits another one
+  with a similar name is found
+  ([#867](https://github.com/go-task/task/issues/867), [#880](https://github.com/go-task/task/pull/880)).
+- Now YAML parse errors will print which Taskfile failed to parse
+  ([#885](https://github.com/go-task/task/issues/885), [#887](https://github.com/go-task/task/pull/887)).
+- Add ability to set `aliases` for tasks and namespaces ([#268](https://github.com/go-task/task/pull/268), [#340](https://github.com/go-task/task/pull/340), [#879](https://github.com/go-task/task/pull/879)).
+- Improvements to Fish shell completion
+  ([#897](https://github.com/go-task/task/pull/897)).
+- Added ability to set a different watch interval by setting
+  `interval: '500ms'` or using the `--interval=500ms` flag
+  ([#813](https://github.com/go-task/task/issues/813), [#865](https://github.com/go-task/task/pull/865)).
+- Add colored output to `--list`, `--list-all` and `--summary` flags ([#845](https://github.com/go-task/task/pull/845), [#874](https://github.com/go-task/task/pull/874)).
+- Fix unexpected behavior where `label:` was being shown instead of the task
+  name on `--list`
+  ([#603](https://github.com/go-task/task/issues/603), [#877](https://github.com/go-task/task/pull/877)).
+
+## v3.16.0 - 2022-09-29
+
+- Add `npm` as new installation method: `npm i -g @go-task/cli`
+  ([#870](https://github.com/go-task/task/issues/870), [#871](https://github.com/go-task/task/pull/871), [npm package](https://www.npmjs.com/package/@go-task/cli)).
+- Add support to marking tasks and includes as internal, which will hide them
+  from `--list` and `--list-all`
+  ([#818](https://github.com/go-task/task/pull/818)).
+
+## v3.15.2 - 2022-09-08
+
+- Fix error when using variable in `env:` introduced in the previous release
+  ([#858](https://github.com/go-task/task/issues/858), [#866](https://github.com/go-task/task/pull/866)).
+- Fix handling of `CLI_ARGS` (`--`) in Bash completion
+  ([#863](https://github.com/go-task/task/pull/863)).
+- On zsh completion, add ability to replace `--list-all` with `--list` as
+  already possible on the Bash completion
+  ([#861](https://github.com/go-task/task/pull/861)).
+
+## v3.15.0 - 2022-09-03
+
+- Add new special variables `ROOT_DIR` and `TASKFILE_DIR`. This was a highly
+  requested feature
+  ([#215](https://github.com/go-task/task/issues/215), [#857](https://github.com/go-task/task/pull/857), [Documentation](https://taskfile.dev/api/#special-variables)).
+- Follow symlinks on `sources`
+  ([#826](https://github.com/go-task/task/issues/826), [#831](https://github.com/go-task/task/pull/831)).
+- Improvements and fixes to Bash completion
+  ([#835](https://github.com/go-task/task/pull/835), [#844](https://github.com/go-task/task/pull/844)).

+- Always resolve relative include paths relative to the including Taskfile
+  ([#822](https://github.com/go-task/task/issues/822), [#823](https://github.com/go-task/task/pull/823)).
+- Fix ZSH and PowerShell completions to consider all tasks instead of just the
+  public ones (those with descriptions)
+  ([#803](https://github.com/go-task/task/pull/803)).
+
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the

+
+# Contributing
+
+Contributions to Task are very welcome, but we ask that you read this document
+before submitting a PR.
+
+## Before you start
+
+- **Check existing work** - Is there an existing PR? Are there issues discussing
+the feature/change you want to make? Please make sure you consider/address these
+discussions in your work.
+- **Backwards compatibility** - Will your change break existing Taskfiles? It is
+much more likely that your change will merged if it backwards compatible. Is
+there an approach you can take that maintains this compatibility? If not,
+consider opening an issue first so that API changes can be discussed before you
+invest you time into a PR.
+
+## 1. Setup
+
+- **Go** - Task is written in [Go]. We always support the latest two major Go
+  versions, so make sure your version is recent enough.
+- **Node.js** - [Node.js] is used to host Task's documentation server and is
+  required if you want to run this server locally.
+- **Yarn** - [Yarn] is the Node.js package manager used by Task.
+
+## 2. Making changes
+
+- **Code style** - Try to maintain the existing code style where possible and
+  ensure that code is formatted by `gofmt`. We use `golangci-lint` in our CI to
+  enforce a consistent style and best-practise. There's a `lint` command in
+  the Taskfile to run this locally.
+- **Documentation** - Ensure that you add/update any relevant documentation. See
+  the [updating documentation](#updating-documentation) section below.
+- **Tests** - Ensure that you add/update any relevant tests and that all tests
+  are passing before submitting the PR. See the [writing tests](#writing-tests)
+  section below.
+
+### Running your changes
+
+To run Task with working changes, you can use `go run ./cmd/task`. To run a
+development build of task against a test Taskfile in `testdata`, you can use `go
+run ./cmd/task --dir ./testdata/<my_test_dir> <task_name>`.
+
+### Updating documentation
+
+Task uses [Docusaurus] to host a documentation server. This can be setup and run
+locally by using `task docs:setup` and `task docs:start` respectively (requires
+`nodejs` & `yarn`). All content is written in Markdown and is located in the
+`docs/docs` directory. All Markdown documents should have an 80 character line
+wrap limit.
+
+When making a change, consider whether a change to the [Usage Guide](./usage.md)
+is necessary. This document contains descriptions and examples of how to use
+Task features. If you're adding a new feature, try to find an appropriate place
+to add a new section. If you're updating an existing feature, ensure that the
+documentation and any examples are up-to-date. Ensure that any examples follow
+the [Taskfile Styleguide](./styleguide.md).
+
+If you added a new field, command or flag, ensure that you add it to the [API
+Reference](./api_reference.md). New fields also need to be added to the
+[JSON Schema](../static/schema.json). The descriptions for fields in the API
+reference and the schema should match.
+
+### Writing tests
+
+Most of Task's test are held in the `task_test.go` file in the project root and
+this is where you'll most likely want to add new ones too. Most of these tests
+also have a subdirectory in the `testdata` directory where any Taskfiles/data
+required to run the tests are stored.
+
+When making a changes, consider whether new tests are required. These tests
+should ensure that the functionality you are adding will continue to work in the
+future. Existing tests may also need updating if you have changed Task's
+behaviour.
+
+## 3. Committing your code
+
+Try to write meaningful commit messages and avoid having too many commits on
+the PR. Most PRs should likely have a single commit (although for bigger PRs it
+may be reasonable to split it in a few). Git squash and rebase is your friend!
+
+## 4. Submitting a PR
+
+- **Describe your changes** - Ensure that you provide a comprehensive
+  description of your changes.
+- **Issue/PR links** - Link any previous work such as related issues or PRs.
+  Please describe how your changes differ to/extend this work.
+- **Examples** - Add any examples that you think are useful to demonstrate the
+  effect of your changes.
+- **Draft PRs** - If your changes are incomplete, but you would like to discuss
+  them, open the PR as a draft and add a comment to start a discussion. Using
+  comments rather than the PR description allows the description to be updated
+  later while preserving any discussions.
+

+# FAQ
+
+This page contains a list of frequently asked questions about Task.
+
+- [Why won't my task update my shell environment?](#why-wont-my-task-update-my-shell-environment)
+- ['x' builtin command doesn't work on Windows](#x-builtin-command-doesnt-work-on-windows)
+
+## Why won't my task update my shell environment?
+
+This is a limitation of how shells work. Task runs as a subprocess of your
+current shell, so it can't change the environment of the shell that started it.
+This limitation is shared by other task runners and build tools too.
+
+A common way to work around this is to create a task that will generate output
+that can be parsed by your shell. For example, to set an environment variable on
+your shell you can write a task like this:
+
+```yaml
+my-shell-env:
+  cmds:
+    - echo "export FOO=foo"
+    - echo "export BAR=bar"
+```
+
+Now run `eval $(task my-shell-env)` and the variables `$FOO` and `$BAR` will be
+available in your shell.
+
+## 'x' builtin command doesn't work on Windows
+
+The default shell on Windows (`cmd` and `powershell`) do not have commands like
+`rm` and `cp` available as builtins. This means that these commands won't work.
+If you want to make your Taskfile fully cross-platform, you'll need to work
+around this limitation using one of the following methods:
+
+- Use the `{{OS}}` function to run an OS-specific script.
+- Use something like `{{if eq OS "windows"}}powershell {{end}}<my_cmd>` to
+  detect windows and run the command in Powershell directly.
+- Use a shell on Windows that supports these commands as builtins, such as [Git
+  Bash] or [WSL].
+
+We want to make improvements to this part of Task and the issues below track
+this work. Constructive comments and contributions are very welcome!

+### Running a Taskfile from a subdirectory
+
+If a Taskfile cannot be found in the current working directory, it will walk up
+the file tree until it finds one (similar to how `git` works). When running Task
+from a subdirectory like this, it will behave as if you ran it from the
+directory containing the Taskfile.
+
+You can use this functionality along with the special `{{.USER_WORKING_DIR}}`
+variable to create some very useful reusable tasks. For example, if you have a
+monorepo with directories for each microservice, you can `cd` into a
+microservice directory and run a task command to bring it up without having to
+create multiple tasks or Taskfiles with identical content. For example:
+
+```yaml
+version: '3'
+
+tasks:
+  up:
+    dir: '{{.USER_WORKING_DIR}}'
+    preconditions:
+      - test -f docker-compose.yml
+    cmds:
+      - docker-compose up -d
+```
+
+In this example, we can run `cd <service>` and `task up` and as long as the
+`<service>` directory contains a `docker-compose.yml`, the Docker composition will be
+brought up.
+
+### Running a global Taskfile
+
+If you call Task with the `--global` (alias `-g`) flag, it will look for your
+home directory instead of your working directory. In short, Task will look for
+a Taskfile on either `$HOME/Taskfile.yml` or `$HOME/Taskfile.yaml` paths.
+
+This is useful to have automation that you can run from anywhere in your
+system!
+
+:::info
+
+When running your global Taskfile with `-g`, tasks will run on `$HOME` by
+default, and not on your working directory!
+
+As mentioned in the previous section, the `{{.USER_WORKING_DIR}}` special
+variable can be very handy here to run stuff on the directory you're calling
+`task -g` from.
