## Creating Documentation

### Guidelines

*   See the [Chromium Documentation Guidelines](https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/documentation_guidelines.md)
    and the
    [Chromium Documentation Best Practices](https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/documentation_best_practices.md).
*   Markdown documents must follow the
    [style guide](https://github.com/google/styleguide/tree/gh-pages/docguide).

### Previewing changes

#### Locally using [md_browser](https://chromium.googlesource.com/chromium/src/+/refs/heads/main/tools/md_browser)

Assuming that `/path/to/src` contains a chromium checkout, you can run:

```bash
# in devtools-frontend checkout
/path/to/src/tools/md_browser/md_browser.py --directory $PWD/docs
```

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
    [preview](https://chromium.googlesource.com/chromium/src/+/ad44f6081ccc6b92479b12f1eb7e9482f474859d/docs/README.md)
    -> Patchset 3
    [preview](https://chromium.googlesource.com/chromium/src/+/refs/changes/32/3362532/3/docs/README.md)
    | DOWNLOAD <br>
    at the top left of the page. Click on the second
    "[preview](https://chromium.googlesource.com/chromium/src/+/refs/changes/32/3362532/3/docs/README.md)"
    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.
