 ### Setup
 
+**1. Disable auto-delete head branches**
+
+The action manages branch deletion itself. GitHub's auto-delete setting must be disabled:
+
+**Via Settings:**
+- Go to your repository Settings → General → Pull Requests
+- Uncheck "Automatically delete head branches"
+
+**Via GitHub CLI:**
+```bash
+gh api -X PATCH "/repos/OWNER/REPO" --input - <<< '{"delete_branch_on_merge":false}'
+```
+
+**2. Add the workflow**
+
 Create a `.github/workflows/update-pr-stack.yml` file:
