+# * This GitHub Actions workflow builds and pushes a Docker image to GitHub Container Registry.
+# * It is triggered when a branch is created with the name syntax "release/[version]-[channel]".
+#
+# The workflow does the following:
+# 1. Checks out the code, sets up Docker buildx, Login to the registry.
+# 2. Extracts the branch name from the GITHUB_REF environment variable.
+# 3. Splits the branch name to get the version and channel.
+# 4. Builds and pushes the Docker image.
+
+# Examples:
+# If the branch name is 'release/1.0.0-latest', the image is tagged as '1.0.0' and 'latest'.
+# If the branch name is 'release/1.0.1-stable', the image is tagged as '1.0.1' and 'stable'.
+# If the branch name is 'release/1.0.2-dev', the image is tagged as '1.0.2-dev'.
+#
+# * The 'latest' and 'stable' tags allow us to easily switch between different versions.
+# *  The 'dev' tag allows you to have a separate version for development.
