+# GitHub Action: Cherry-pick from `release/candidate` to `TARGET_BRANCH`
+#
+# This action automates the process of cherry-picking merged PRs from `release/candidate` branch to `TARGET_BRANCH`.
+# It is triggered whenever a pull request is merged into `release/candidate`.
+#
+# The action performs the following steps:
+# 1. Checkout the merged PR.
+# 2. If changes are made outside the specified submodule or no submodule is specified, the action proceeds.
+# 3. If a submodule name is provided in the `SUBMODULE_NAME` environment variable:
+#    a. The action creates a temporary branch.
+#    b. Updates the submodule to its latest version from `develop`.
+#    c. Commits the submodule updates.
+# 4. Squashes the commit with the commit message of the merged PR (if a submodule was updated).
+# 5. Cherry-picks the squashed (or original if no squashing occurred) commit to a new branch based on `develop`.
+# 6. If any conflicts arise during the cherry-pick, they are committed.
+# 7. The branch with the cherry-picked changes is pushed.
+# 8. A new pull request is created against `develop` with the cherry-picked changes.
+#
+# Note: Ensure you add a "cherry-pick" label to your project. This label is required for the creation of cherry-picked PRs.
+# If needed, you can also set the `TARGET_BRANCH` environment variable to specify a different target branch for the cherry-pick.
+# By default, it's set to `develop`.
