Linking

The Documentation module supports relative links and cross-linking between pages in documentation.

Relative Links

Within a given module's documentation, you can use relative links between files. These will be resolved during the rendering of the documentation.

For example, to link to a document in the same directory called doc.md, you can format your link as:

Consult the [documentation](./doc.md)

To link to a document in a subdirectory or a parent directory, use similar relative links with the directory names:

[Document in the parent directory](../doc.md)

[Document in a subdirectory](./subdir/doc.md)

Note that relative links can only be used between documents in a single module, and links to other modules should instead use cross-linking.

Cross-Linking

Cross-linking refers to links from one module to another. This allows creating richer documentation, tying together various modules.

To link from one module to another, use the special URL scheme docs://. This should be followed by the name of the documentation group (typically the module ID), followed by a slash, followed by the page ID (typically a file path within the module's documentation directory). The full format is:

docs://{group}/{id}

For example, to link to the branding.md document in the CMS module (ID cms):

Consult the [branding documentation](docs://cms/branding.md)

Note: while documentation group IDs generally align with module IDs, some special groups exist for meta documentation. This includes the Getting Started (ID getting-started) and Guides (ID guides) documentation, which are located in the other-docs directory of the Documentation module.

Internal Linking

To enable rich documentation, you can link to internal resources on the site.

These links use the special internal:// URL scheme. This is followed by the type of internal link, followed by a slash, followed by an optional additional path. The following types are available:

• internal://home/{path} - URL on the frontend, equivalent to home_url( $path )
• internal://site/{path} - URL on the backend, equivalent to site_url( $path )
• internal://admin/{path} - Page in the admin, equivalent to admin_url( $path )
• internal://network-admin/{path} - Page in the network admin, equivalent to network_admin_url( $path )

For example, to link to the current user's profile page:

[View your profile](internal://admin/profile.php)
