+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for the React Native Windows repository.
+
+## Available Workflows
+
+### Cherry-pick Commit to Branch
+
+**File:** `cherry-pick-commit.yml`
+
+Cherry-picks a specific commit into a target branch.
+
+**Usage:**
+
+1. Go to the Actions tab in the GitHub repository
+2. Select "Cherry-pick Commit to Branch" workflow
+3. Click "Run workflow"
+4. Enter the required inputs:
+   - **Commit SHA or ID**: The full commit hash or short SHA of the commit to cherry-pick
+   - **Target branch name**: The branch where you want to cherry-pick the commit
+
+**Example:**
+
+- Commit ID: `d1a95351e5203a6c0651cf73885cd7ea99e7d2b9`
+- Target branch: `0.79-stable`
+
+**Notes:**
+
+- The workflow will fail if there are merge conflicts during cherry-pick
+- If conflicts occur, you'll need to resolve them manually
+- The commit will be pushed directly to the target branch after successful cherry-pick
