 ## Keeping the PR checks up to date (admin access required)
 
-Since the `codeql-action` runs most of its testing through individual Actions workflows, there are over two hundred jobs that need to pass in order for a PR to turn green. You can regenerate the checks automatically by running the [update-required-checks.sh](.github/workflows/script/update-required-checks.sh) script:
+Since the `codeql-action` runs most of its testing through individual Actions workflows, there are over two hundred jobs that need to pass in order for a PR to turn green. You can regenerate the required checks automatically by running the [update-required-checks.sh](.github/workflows/script/update-required-checks.sh) script:
 
 1. By default, this script retrieves the checks from the latest SHA on `main`, so make sure that your `main` branch is up to date.
 2. Run the script. If there's a reason to, you can pass in a different SHA as a CLI argument.
-3. After running, go to the [branch protection rules settings page](https://github.com/github/codeql-action/settings/branches) and validate that the rules for `main`, `v1`, and `v2` have been updated.
