 Some notes on GitHub PRs:
 - [Convert your PR as a draft](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/changing-the-stage-of-a-pull-request) if your changes are a work in progress: no one will review it until you pass your PR as ready for review.<br>
   The draft PR can be very useful if you want to show that you are working on something and make your work visible.
-- The branch related to the PR must be **up-to-date with `master`** before merging. You need to [rebase your branch](https://gist.github.com/curquiza/5f7ce615f85331f083cd467fc4e19398) if it is not.
+- The branch related to the PR must be **up-to-date with `master`** before merging. [Bors](https://github.com/bors-ng/bors-ng) will rebase your branch if it is not. Ask a maintainer to run it.
 - All PRs must be reviewed and approved by at least one maintainer.
 - All PRs have to be **squashed and merged**.
 - The PR title should be accurate and descriptive of the changes. The title of the PR will be indeed automatically added to the next [release changlogs](https://github.com/meilisearch/meilisearch-ruby/releases/).
