 - If you're deploying documentation updates, verify that the documentations work properly once the deploy is done. Keep in mind that you'll need to wait a few seconds for the service worker to finish caching the new assets. You should see a "DevDocs has been updated" notification appear when the caching is done, after which you need to refresh the page to see the changes.
