 We merge all pull requests in `squash merge` mode. You're not enforced to use [conventional commit standard](https://www.conventionalcommits.org/en/v1.0.0-beta.2/#why-use-conventional-commits) across all your commits, but it's a good practice and increase transparency. At the end it's important that the squashed commit message follow the standard.
 
+When updating your branch after a review has been requested, prefer using a merge strategy (e.g. `git merge main`) rather than rebasing. This preserves the review context and avoids force-pushes that can disrupt the review process.
