+
+## Description
+
+The `dsc extension` command contains a subcommand for listing DSC extensions.
+
+## Commands
+
+### list
+
+The `list` command returns the list of available DSC extensions with an optional filter. For more
+information, see [dsc extension list][01].
+
+### help
+
+The `help` command returns help information for this command or a subcommand.
+
+To get the help for a command or subcommand, use the syntax:
+
+```sh
+dsc extension help [<SUBCOMMAND>]
+```
+
+For example, `dsc extension help` gets the help for this command. `dsc extension help list`
+gets the help for the `list` subcommand.
+
+You can also use the [--help](#--help) option on the command or subcommand to display the help
+information. For example, `dsc extension --help` or `dsc extension list --help`.
+

+# dsc extension list
+
+## Synopsis
+
+Retrieves the list of available DSC extensions with an optional filter.
+
+## Syntax
+
+```sh
+dsc extension list [Options] <EXTENSION_NAME>
+```
+
+## Description
+
+The `list` subcommand searches for available DSC extensions and returns their information. DSC
+discovers extensions by first searching the `PATH` or `DSC_RESOURCE_PATH` environment variable for
+`.dsc.extension.json`, `.dsc.extension.yml`, and `dsc.extension.yaml` files. For more information
+about the environment variables DSC uses, see [Environment variables][01]
+
+DSC returns the list of discovered extensions with their implementation information and metadata. If
+the command includes the `EXTENSION_NAME` argument, DSC filters the list of discovered extensions
+before returning them. Filters are always applied after extension discovery.
+
+## Examples
+
+### Example 1 - List all extensions
+
+Without any filters, the command returns every discovered DSC extension.
+
+```sh
+dsc extension list
+```
+
+```Output
+Type                             Version  Capabilities  Description
+----------------------------------------------------------------------------------------------------------
+Microsoft.Windows.Appx/Discover  0.1.0    d             Discovers DSC resources packaged as Appx packages.
+```
+
+### Example 2 - List a specific extension
+
+When the `EXTENSION_NAME` argument doesn't include a wildcard, the command returns only the extension
+with the specified type name.
+
+```sh
+dsc extension list Microsoft.Windows.Appx/Discover
+```
+
+```Output
+Type                             Version  Capabilities  Description
+----------------------------------------------------------------------------------------------------------
+Microsoft.Windows.Appx/Discover  0.1.0    d             Discovers DSC resources packaged as Appx packages.
+```
+
+### Example 3 - List extensions with a matching type name
+
+When the `EXTENSION_NAME` argument includes a wildcard, the command returns every extension with a
+matching type name.
+
+```sh
+dsc extension list Microsoft*
+```
+
+```Output
+Type                             Version  Capabilities  Description
+----------------------------------------------------------------------------------------------------------
+Microsoft.Windows.Appx/Discover  0.1.0    d             Discovers DSC resources packaged as Appx packages.
+```
+
+## Arguments
+
+### EXTENSION_NAME
+
+Specifies an optional filter to apply for the type names of discovered DSC extensions. The filter
+can include wildcards (`*`). The filter isn't case-sensitive.
+
+When this argument is specified, DSC filters the results to include only extensions where the
+extension type name matches the filter.
+
+For example, specifying the filter `Microsoft.*` returns only the extensions published by
+Microsoft. Specifying the filter `*Windows*` returns any extension with the string `Windows` in its
+name, regardless of the casing.
+
+```yaml
+Type      : string
+Mandatory : false
+```
+
+## Options
+
+### -o, --output-format
+
+<a id="-o"></a>
+<a id="--output-format"></a>
+
+The `--output-format` option controls which format DSC uses for the data the command returns. The
+available formats are:
+
+- `json` to emit the data as a [JSON Line][02].
+- `pretty-json` to emit the data as JSON with newlines, indentation, and spaces for readability.
+- `yaml` to emit the data as YAML.
+- `table-no-truncate` to emit the data as a summary table without truncating each line to the
+  current console width.
+
+The default output format depends on whether DSC detects that the output is being redirected or
+captured as a variable:
+
+- If the command isn't being redirected or captured, DSC displays the output as a summary table
+  described in the [Output](#output) section of this document.
+- If the command output is redirected or captured, DSC emits the data as the `json` format to
+  stdout.
+
+When you use this option, DSC uses the specified format regardless of whether the command is being
+redirected or captured.
+
+When the command isn't redirected or captured, the output in the console is formatted for improved
+readability. When the command isn't redirected or captured, the output includes terminal sequences
+for formatting.
+
+```yaml
+Type        : string
+Mandatory   : false
+ValidValues : [json, pretty-json, yaml, table-no-truncate]
+LongSyntax  : --output-format <OUTPUT_FORMAT>
+ShortSyntax : -o <OUTPUT_FORMAT>
+```
+
+### -h, --help
+
+<a id="-h"></a>
+<a id="--help"></a>
+
+Displays the help for the current command or subcommand. When you specify this option, the
+application ignores all other options and arguments.
+
+```yaml
+Type        : boolean
+Mandatory   : false
+LongSyntax  : --help
+ShortSyntax : -h
+```
+
+## Output
+
+This command returns a formatted array containing an object for each extension that includes the
+extension's type, version, manifest settings, and other metadata. For more information, see
+[dsc extension list result schema][03].
+
+If the output of the command isn't captured or redirected, it displays in the console by default as
+a summary table for the returned extensions. The summary table includes the following columns,
+displayed in the listed order:
+
+- **Type** - The fully qualified type name of the extension.
+- **Version** - The semantic version of the extension.
+- **Capabilities** - A display of the extension's [capabilities][04] as flags. The capabilities are
+  displayed in the following order, using a `-` instead of the appropriate letter if the extension
+  doesn't have a specific capability:
+
+  - `d` indicates that the extension has the [discover capability][05].
+
+  For example, the `icrosoft.Windows.Appx/Discover` extension has the following capabilities: `d`,
+  indicating it has the `discover` capability.
+- **Description** - The short description of the extension's purpose and usage.
+
+For more information about the formatting of the output data, see the
+[--output-format option](#--output-format).
