+# MkDocs Site URLs
+
+A MkDocs plugin that adds support for site-relative `site:` URLs.
+
+Example:
+
+| URL | site_url | resulting URL |
+| --- | -------- | ------------- |
+| `site:images/foo.png` | `https://example.com/` | `/images/foo.png` |
+| `site:images/foo.png` | `https://example.com/bar/` | `/bar/images/foo.png` |
+
+## Usage
+
+1. Install the plugin from PyPI
+   ```bash
+   pip install mkdocs-site-urls
+   ```
+2. Add the `site-urls` plugin to your `mkdocs.yml` plugins section:
+   ```yaml
+   plugins:
+     - site-urls
+   ```
+   There are no configuration options.
+3. Start using site-relative URLs in your Markdown files by prefixing them with `site:`:
+   ```markdown
+   [Link to another page](site:another-page/relative/to/the/site/root)
+
+   ![Image](site:images/foo.png)
+   ```
+
+## How it works
+
+The plugin hooks into the [`on_page_content` event](https://www.mkdocs.org/dev-guide/plugins/#on_page_content)
+and replaces all URLs in `href` or `src` attributes in the rendered HTML with the corresponding site-relative URLs.
+
