+Hi, thanks for contributing to Strawberry 🍓! We noticed that this PR\
+is missing a `RELEASE.md` file. We use that to automatically\
+do releases here on GitHub and, most importantly, to PyPI!
+
+So as soon as this PR is merged, a release will be made 🚀.
+
+Here's an example of `RELEASE.md`:
+
+```markdown
+Release type: patch
+
+Description of the changes, ideally with some examples, if adding a new feature.
+```
+
+Release type can be one of patch, minor or major. We use [semver](https://semver.org/),\
+so make sure to pick the appropriate type. If in doubt feel free to ask :)
