+## Reviewing and merging dependency refreshes
+
+At the start of each week the `.github/workflows/pip-compile-*` workflows run.
+These workflows bump dependencies and create pull requests such as [PR 2842](https://github.com/ansible/ansible-documentation/pull/2842).
+
+PRs to bump dependencies should be merged in a timely fashion.
+The documentation repo categorizes dependencies into separate requirements files.
+The weekly schedule for workflow runs also ensures fewer dependencies are bumped at a time.
+This granularity and isolation helps us detect incompatibilities and issues that a new version of a dependency might introduce.
+
+When reviewing PRs to refresh dependencies, look at the files changed and note the name of the requirements file.
+This corresponds to a check in CI; for example `tests/static.txt` contains the dependencies for the `nox / Run nox static session` check.
+
+In general, CI check will emit errors or warnings if the dependency refresh introduces an issue of some kind.
+So basically, during review, expand the CI checks and look for problems in the output of the relevant steps.
+If there are no errors, warnings or other messages and the step has run successfully, the dependency bump should be fine to approve and merge.
+
+In most cases, when a dependency refresh causes an issue, you probably need to adjust something in the appropriate session in `noxfile.py`.
+For example, [PR 1172](https://github.com/ansible/ansible-documentation/pull/1172) bumped the version of `ruff` which resulted in a warning because the `static` session included a deprecated command.
+To fix the issue, [PR 1191](https://github.com/ansible/ansible-documentation/pull/1191) updated the `ruff` command and was merged before [PR 1172](https://github.com/ansible/ansible-documentation/pull/1172).
