 We're really happy to accept contributions. However we also ask that you follow several rules when doing so.
 
 # Proper base
-When opening a PR, please make sure your branch targets the latest release branch, in this case it would be `main`. Also make sure your branch is even with the target branch, to avoid unnecessary surprises.

 # Versioning
 We follow [SemVer](https://semver.org/) versioning when it comes to pushing stable releases. Ideally, this means you should only be creating PRs for `patch` and `minor` changes. If you wish to introduce a `major` (breaking) change, please discuss it beforehand so we can determine how to integrate it into our next major version. If this involves removing a public facing property/method, mark it with the `Obsolete` attribute instead on the latest release branch.
