 ### Links to documentation
 
-Links to other pages in the documentation uses the URL slug, *not* the file name.
+When updating documentation for [`silverstripe/developer-docs`](https://github.com/silverstripe/developer-docs/), which is the content repository for [`docs.silverstripe.org`](https://docs.silverstripe.org), links to other pages in the documentation should use the URL slug, not the file name.
+
+When updating docs that are in a modules `docs/en` folder, and will be shown in the "Optional features" section of `docs.silverstripe.org`, and are also intended to be readible on GitHub, then links to other pages should use a relative path to the file name, not the URL slug.
 
 Relative documentation links are prefixed with `./` for pages in the same directory, or `../` for pages in parent directories. For example `[contributing code](./code)` becomes [contributing code](./code) and `[getting started](../getting_started)` becomes [getting started](../getting_started).
 
 Absolute documentation links are preferred for pages which aren't in the same directory or one level up. The language and version number are ommitted. For example `[managing lists](/developer_guides/model/lists/)` becomes [managing lists](/developer_guides/model/lists/).
 
+### Images
+
+Add images, such as screenshots, to an `_images` directory which should usually be located at `docs/en/_images`. Use relative links these files and use the markdown syntax `![Some alt text](_images/some-file.jpg)`. You must include alt text. Adding images this way will work correctly on both markdown added to `silverstripe/developer-docs`, and also to `docs/en` folder for a module that dispays on both `docs.silverstripe.org` and GitHub.
