+### How to release
+Hint: for technical details regarding the release process have a look into .github/...  
+To create a release these steps need to be followed
+1. make sure all needed code changes are merged from dev -> stage -> prod, since releases may only be build on prod branch
+2. give pull requests meaningful names and label them enhancement/bug/chore since labels and names are used for release note generation
+    Hint: if a specific pull request should be ignored, add the label changelog-ignore
+3. tag a commit (recommended is the latest merge on prod). The pipeline is listening for any tag fitting `v[0-9]+.[0-9]+.[0-9]+`
+    ```shell
+      git tag -a v1.2.3 1a2b3c4 -m "Release version 1.2.3"
+    ```
+4. push the tag 
+    ```shell
+      git push origin --tags
+    ```
+5. the tag push will trigger the pipeline, and it will create the release and store in GitHub
+
+A release can be created again anytime by deleting the release from GitHub, deleting the tag (from GitHub and additionally from git)
+and repeating step 3 and 4
