### Additional features
- Support images (e.g: `![Image](./image.png)`).
- Support anchors (heading fragment links) (e.g: `[Link](./awesome.md#existing-heading)`).
- Support links fragments similar to the [built-in `markdownlint` rule - MD051](https://github.com/DavidAnson/markdownlint/blob/main/doc/md051.md) (e.g: `[Link](./awesome.md#heading)`).
- Ignore external links and absolute paths as it only checks relative links (e.g: `https://example.com/` or `/absolute/path.png`).
### Limitations
- Only images and links defined using markdown syntax are validated, html syntax is not supported (e.g: `<a href="./link.txt" />` or `<img src="./image.png" />`).
- Anchors checking is limited to headings, other elements are not supported (e.g: with a "id", `<div id="anchor" />`).
- Only images and links defined using markdown syntax are validated, html syntax is ignored (e.g: `<a href="./link.txt" />` or `<img src="./image.png" />`).
Contributions are welcome to improve the rule, and to alleviate these limitations. See [CONTRIBUTING.md](./CONTRIBUTING.md) for more information.
