+## Docs Pages
 
-Starlight looks for `.md` or `.mdx` files in the `src/content/docs/` directory. Each file is exposed as a route based on its file name.
+Each page in the docs is a markdown file located at content/docs/...
 
-Images can be added to `src/assets/` and embedded in Markdown with a relative link.
+To edit a docs page, simply edit the markdown file.
 
-Static assets, like favicons, can be placed in the `public/` directory.
