+## Schema
+
+### Taskfile
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `version` | `string` | | Version of the Taskfile. The current version is `3`. |
+| `includes` | [`map[string]Include`](#include) | | Additional Taskfiles to be included. |
+| `output` | `string` | `interleaved` | Output mode. Available options: `interleaved`, `group` and `prefixed`. |
+| `method` | `string` | `checksum` | Default method in this Taskfile. Can be overriden in a task by task basis. Available options: `checksum`, `timestamp` and `none`. |
+| `silent` | `bool` | `false` | Default "silent" options for this Taskfile. If `false`, can be overidden with `true` in a task by task basis. |
+| `run` | `string` | `always` | Default "run" option for this Taskfile. Available options: `always`, `once` and `when_changed`. |
+| `vars` | [`map[string]Variable`](#variable) | | Global variables. |
+| `env` | [`map[string]Variable`](#variable) | | Global environment. |
+| `dotenv` | `[]string` | | A list of `.env` file paths to be parsed. |
+| `tasks` | [`map[string]Task`](#task) | | The task definitions. |
+
+
+### Include
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `taskfile` | `string` | | The path for the Taskfile or directory to be included. If a directory, Task will look for files named `Taskfile.yml` or `Taskfile.yaml` inside that directory. |
+| `dir` | `string` | The parent Taskfile directory | The working directory of the included tasks when run. |
+| `optional` | `bool` | `false` | If `true`, no errors will be thrown if the specified file does not exist. |
+
+:::info
+
+Informing only a string like below is equivalent to setting that value to the `taskfile` attribute.
+
+```yaml
+includes:
+  foo: ./path
+```
+
+:::
+
+### Task
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `desc` | `string` | | A short description of the task. This is listed when calling `task --list`. |
+| `summary` | `string` | | A longer description of the task. This is listed when calling `task --summary [task]`. |
+| `sources` | `[]string` | | List of sources to check before running this task. Relevant for `checksum` and `timestamp` methods. Can be file paths or star globs. |
+| `dir` | `string` | | The current directory which this task should run. |
+| `method` | `string` | `checksum` | Method used by this task. Default to the one declared globally or `checksum`. Available options: `checksum`, `timestamp` and `none` |
+| `silent` | `bool` | `false` | Skips some output for this task. Note that STDOUT and STDERR of the commands will still be redirected. |
+| `run` | `string` | The one declared globally in the Taskfile or `always` | Specifies whether the task should run again or not if called more than once. Available options: `always`, `once` and `when_changed`. |
+| `prefix` | `string` | | Allows to override the prefix print before the STDOUT. Only relevant when using the `prefixed` output mode. |
+| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the commands. |
+| `generates` | `[]string` | | List of files meant to be generated by this task. Relevant for `timestamp` method. Can be file paths or star globs. |
+| `status` | `[]string` | | List of commands to check if this task should run. The task is skipped otherwise. This overrides `method`, `sources` and `generates`. |
+| `preconditions` | [`[]Precondition`](#precondition) | | List of commands to check if this task should run. The task errors otherwise. |
+| `vars` | [`map[string]Variable`](#variable) | | Task variables. |
+| `env` | [`map[string]Variable`](#variable) | | Task environment. |
+| `deps` | [`[]Dependency`](#dependency) | | List of dependencies of this task. |
+| `cmds` | [`[]Command`](#command) | | List of commands to be executed. |
+
+:::info
+
+These alternative syntaxes are available. They will set the given values to
+`cmds` and everything else will be set to their default values:
+
+```yaml
+tasks:
+  foo: echo "foo"
+
+  foobar:
+    - echo "foo"
+    - echo "bar"
+```
+
+:::
+
+### Dependency
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `task` | `string` | | The task to be execute as a dependency. |
+| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to this task. |
+
+:::tip
+
+If you don't want to set additional variables, it's enough to declare the
+dependency as a list of strings (they will be assigned to `task`):
+
+```yaml
+tasks:
+  foo:
+    deps: [foo, bar]
+```
+
+:::
+
+### Command
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `cmd` | `string` | | The shell command to be executed. |
+| `defer` | `string` | | Alternative to `cmd`, but schedules the command to be executed at the end of this task instead of immediately. This cannot be used together with `cmd`. |
+| `silent` | `bool` | `false` | Skips some output for this command. Note that STDOUT and STDERR of the commands will still be redirected. |
+| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the command. |
+| `task` | `string` | | Set this to trigger execution of another task instead of running a command. This cannot be set together with `cmd`. |
+| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to the referenced task. Only relevant when setting `task` instead of `cmd`. |
+
+:::info
+
+If given as a a string, the value will be assigned to `cmd`:
+
+```yaml
+tasks:
+  foo:
+    cmds:
+      - echo "foo"
+      - echo "bar"
+```
+
+:::
+
+### Variable
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| *itself* | `string` | | A static value that will be set to the variable. |
+| `sh` | `string` | | A shell command. The output (`STDOUT`) will be assigned to the variable. |
+
+:::info
+
+Static and dynamic variables have different syntaxes, like below:
+
+```yaml
+vars:
+  STATIC: static
+  DYNAMIC:
+    sh: echo "dynamic"
+```
+
+:::
+
+### Precondition
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `sh` | `string` | | Command to be executed. If a non-zero exit code is returned, the task errors without executing its commands. |
+| `msg` | `string` | | Optional message to print if the precondition isn't met. |
+
+:::tip
+
+If you don't want to set a different message, you can declare a precondition
+like this and the value will be assigned to `sh`:
+
+```yaml
+tasks:
+  foo:
+    precondition: test -f Taskfile.yml
+```
