## Creating Documentation

### Guidelines

*   See the [Chromium Documentation Guidelines](documentation_guidelines.md)
    and the
    [Chromium Documentation Best Practices](documentation_best_practices.md).
*   Markdown documents must follow the
    [Markdown Style
    Guide](https://chromium.googlesource.com/chromium/src/+/HEAD/styleguide/markdown/markdown.md).

### Previewing changes

#### Locally using [md_browser](../tools/md_browser/)

```bash
# in chromium checkout
./tools/md_browser/md_browser.py
```

This is only an estimate. The **gitiles** view may differ.

#### Online with Gerrit's links to gitiles

1.  Upload a patch to gerrit, or receive a review request.
    e.g. https://chromium-review.googlesource.com/c/3362532
2.  View a specific .md file.
    e.g. https://chromium-review.googlesource.com/c/3362532/2/docs/README.md
3.  You will see something like <br>
    Base

    link to open the preview for the current patch set.

This **gitiles** view is the authoritative view, exactly the same as will be
used when committed.
