+Steps when releasing openeo-grassgis-driver:
+
+## 1. Prepare release and version
+* Run in terminal
+    ```
+    ESTIMATED_VERSION=2.5.1
+
+    gh api repos/Open-EO/openeo-grassgis-driver/releases/generate-notes -f tag_name="$ESTIMATED_VERSION" -f target_commitish=main -q .body
+    ```
+* Go to https://github.com/Open-EO/openeo-grassgis-driver/releases/new
+* Copy the output of terminal command to the release description
+* Change heading `## What's Changed` to `### Changed`, `### Fixed`, `### Added` or what applicable and sort list amongst these headings.
+* You can [compare manually](https://github.com/Open-EO/openeo-grassgis-driver/compare/2.5.1...2.5.0) if all changes are included. If changes were pushed directly to main branch, they are not included.
+* Check if `ESTIMATED_VERSION` increase still fits - we follow [Semantic Versioning](https://semver.org/spec/v2.0.0.html)
+* Fill in tag and release title with this version
+* At the bottom of the release, add
+  "generated with `gh api repos/Open-EO/openeo-grassgis-driver/releases/generate-notes -f tag_name="$ESTIMATED_VERSION" -f target_commitish=main -q .body`" and replace `$ESTIMATED_VERSION` with the actual version.
+
+## 3. Release
+* Now you can save the release
+
+## 4. Update changelog
+* Run in terminal
+    ```
+    curl https://api.github.com/repos/Open-EO/openeo-grassgis-driver/releases/latest | jq -r '. | "## [\(.tag_name)] - \(.published_at | strptime("%Y-%m-%dT%H:%M:%SZ") | strftime("%Y-%m-%d"))\nreleased from \(.target_commitish)\n\(.body) \n"'
+    ```
+* Copy the output to the top of the release list in [CHANGELOG.rst](https://github.com/Open-EO/openeo-grassgis-driver/blob/main/CHANGELOG.rst)
+* Push changes in CHANGELOG.rst to main branch
