 1. Find a suitable Chromium revision
    Not all revisions have builds for all platforms, so we need to find one that does.
-   To do so, run `utils/check_availability.js -rb` to find the latest suitable beta Chromium revision (see `utils/check_availability.js -help` for more options).
+   To do so, run `utils/check_availability.js -rd` to find the latest suitable `dev` Chromium revision (see `utils/check_availability.js -help` for more options).
 1. Update `src/revisions.ts` with the found revision number.
 1. Update `versions.js` with the new Chromium-to-Puppeteer version mapping.
 1. Run `npm run ensure-correct-devtools-protocol-revision`.
    If it fails, update `package.json` with the expected `devtools-protocol` version.

If a test fails, [bisect](#bisecting-upstream-changes) the upstream cause of the failure, and either update the test expectations accordingly (if it was an intended change) or work around the changes in Puppeteer (if it’s not desirable to change Puppeteer’s observable behavior).

    The commit message must contain the version in `Chromium <version> (<revision>)` format to ensure that [pptr.dev](https://pptr.dev/) can parse it correctly, e.g. `'feat(chromium): roll to Chromium 90.0.4427.0 (r856583)'`.
