 # Bitnami Common Library Helm Chart
 
+## Description
+
 This repository contains Bitnami Common Library Helm Chart version `2.2.2` packaged by Bitnami.
 
 The chart is used for OSDU purposes only.
 
 Details on chart usage are available in [Bitnami Common Library Helm Chart README](./chart/README.md).
+
+## Release process
+
+To release Bitnami Common Library Helm Chart the following actions should be performed:
+
+1. New updates to the code should be brought, tested and merged into the `main` branch using Merge Request. For merge request development version of the chart is published that can be used for testing.
+
+2. After merging the updated version into the `main` branch, the appropriate tag should be created on it specifying release version (e.g. `v2.2.3`). This will trigger jobs that will push the packaged chart of specified version to the Google Container Registry and the Gitlab Container Registry in OCI format.
