## Docs structure

We use a mix of markdown and HTML tags to customize the documentation along with an [`extra.css`](https://github.com/carla-simulator/carla/tree/master/Docs/extra.css) file.
To update Python API docs, instead of directly modifying the Markdown you need to edit the corresponding YAML files inside [`carla/PythonAPI/docs/`][fileslink] and run [`doc_gen.py`][scriptlink] or `make PythonAPI.docs`.  

This will re-generate the respective Markdown files inside `carla/Docs/`, which can then be fed into `mkdocs`.

## Rules

*   Leave always an empty line between sections and at the end of the document.
*   Writting should not exceed `100` columns, except for HTML related content, markdown tables, code snipets and referenced links.
*   If an inline link exceeds the limit, use referenced `[name][reference_link]` markdown notation `[reference_link]: https://` rather than `[name](https://)`.
*   Use `<br>` to make inline jumps rather than leaving two spaces at the end of a line.
*   Use `<h1>Title</h1>` at the beggining of a new page in order to make a Title or `<hx>Heading<hx>` to make a heading that **won't show** on the navigation bar.
*   Use `------` underlining a Heading or `#` hierarchy to make headings and show them in the navigation bar.

---
## Exceptions

  * Documentation generated via Python scripts like PythonAPI reference
