 1. When making links to the API, copy actual links from [GitHub](https://github.com/microsoft/playwright/blob/master/docs/api.md), and not from `api.md` source - these might be incorrect.
     - Before publishing, replace `blob/master/docs` with `blob/vX.Y.Z/docs` in all the links.
 1. Use "Save Draft", not "Publish".
