+## Releasing
+The Microgateway Helm Chart is automatically released when a pull request is merged into the master branch if the following conditions are true:
+- There are actual changes in the chart.
+- The chart version is incremented.
+
+Make sure that you have updated the artifacthub.io/changes annotation in the Chart.yaml if you plan to release a PR.
+
+### Merging a PR without Releasing
