+
+## Overview
+
+The automated backport workflow simplifies the process of backporting merged PRs from the `master` branch to release branches (e.g., `v0.20.x-branch`, `v0.19.x-branch`).
+
+Instead of manually creating branches, cherry-picking commits, and creating PRs, maintainers can simply add a label to the master PR, and the workflow handles the rest.
+
+## How to Use
+
+### Basic Usage
+
+1. **Merge a PR to master** (or have it already merged)
+2. **Add a backport label** in the format: `backport-v<version>-branch`
+   - Example: `backport-v0.20.x-branch`
+3. **The workflow automatically**:
+   - Validates the target branch exists
+   - Cherry-picks the commits
+   - Creates a new PR targeting the release branch
+   - Adds the `no-changelog` label (since release notes are in the master PR)
+
+### Example Scenario
+
+```
+Day 1, 10:00 - PR #1234 "Fix critical bug" merged to master
+Day 1, 10:30 - Add label: backport-v0.20.x-branch
+Day 1, 10:31 - Workflow creates PR #1235 automatically
+              Title: "[v0.20.x-branch] Backport #1234: Fix critical bug"
+              Base: v0.20.x-branch
+              Labels: no-changelog
+Day 1, 14:00 - Maintainer reviews and merges PR #1235
+```
+
+## Workflow Triggers
+
+The backport workflow triggers in two scenarios:
+
+### Scenario 1: Label Before Merge
+
+```
+1. Open PR #1234
+2. Add label: backport-v0.20.x-branch
+3. Review and approve PR
+4. Merge PR #1234
+5. → Workflow triggers on PR close event
+6. → Backport PR #1235 created immediately
+```
+
+### Scenario 2: Label After Merge
+
+```
+1. Open PR #1234
+2. Review, approve, and merge PR #1234
+3. Later... decide it needs backporting
+4. Add label: backport-v0.20.x-branch
+5. → Workflow triggers on label event
+6. → Backport PR #1235 created immediately
+```
+
+Both scenarios work identically.
+
+## Label Format
+
+### Valid Labels
+
+Labels **must** start with `backport-v` to trigger the workflow:
+
+- ✅ `backport-v0.20.x-branch` → backports to `v0.20.x-branch`
+- ✅ `backport-v0.19.x-branch` → backports to `v0.19.x-branch`
+- ✅ `backport-v0.18.x-beta-branch` → backports to `v0.18.x-beta-branch`
+
+### Invalid Labels (Will NOT Trigger)
+
+These labels are ignored by the workflow:
+
+- ❌ `backport candidate` - discussion label only
+- ❌ `backport-candidate` - doesn't start with `backport-v`
+- ❌ `backport-needed` - doesn't start with `backport-v`
+- ❌ `needs-backport` - wrong prefix
+
+This allows you to use discussion labels without accidentally triggering backports.
+
+### Label to Branch Mapping
+
+The label format directly maps to the target branch:
+
+```
+Label: backport-v0.20.x-branch
+           ↓ (removes "backport-" prefix)
+Branch: v0.20.x-branch
+```
+
+## Workflow Steps
+
+The workflow executes the following steps when triggered:
+
+### Step 1: Checkout Repository
+
+```yaml
+- Fetches the full git history
+- Checks out the base branch (usually master)
+```
+
+### Step 2: Validate Target Branches
+
+```bash
+For each backport label:
+  1. Extract branch name from label
+     backport-v0.20.x-branch → v0.20.x-branch
+
+  2. Check if branch exists in remote repository
+     git ls-remote --heads origin v0.20.x-branch
+
+  3. If branch doesn't exist:
+     - Log error message
+     - Add branch to missing_branches list
+
+  4. After checking all labels:
+     - If any branches are missing → FAIL workflow
+     - If all branches exist → Continue
+```
+
+**Example validation output:**
+
+```
+All labels: ["backport-v0.20.x-branch", "bug-fix", "backport-v0.19.x-branch"]
+Found backport labels:
+backport-v0.20.x-branch
+backport-v0.19.x-branch
+
+Checking if branch exists: v0.20.x-branch
+✓ Branch 'v0.20.x-branch' exists
+
+Checking if branch exists: v0.19.x-branch
+✓ Branch 'v0.19.x-branch' exists
+
+✓ All target branches validated successfully
+```
+
+### Step 3: Create Backport PRs
+
+For each valid backport label, the workflow:
+
+1. **Creates a new branch**
+   - Branch name: `backport-<pr-number>-to-<target-branch>`
+   - Example: `backport-1234-to-v0.20.x-branch`
+   - Based on: the target release branch
+
+2. **Cherry-picks commits**
+   - Uses `git cherry-pick` (not merge or rebase)
+   - Cherry-picks all commits from the original PR
+   - Preserves commit messages and authorship
+   - Skips merge commits
+
+3. **Creates a new PR**
+   - Title: `[v0.20.x-branch] Backport #1234: <original-title>`
+   - Base branch: `v0.20.x-branch`
+   - Head branch: `backport-1234-to-v0.20.x-branch`
+   - Labels: `no-changelog` (automatically added)
+
+4. **PR Description**
+   ```markdown
+   Backport of #1234
+
+   Original PR: https://github.com/lightningnetwork/lnd/pull/1234
+
+   ---
+
+   [Original PR description here]
+   ```
+
+## Handling Conflicts
+
+The workflow handles merge conflicts gracefully using the `draft_commit_conflicts` strategy.
+
+### When Cherry-pick Succeeds
+
+```
+1. Cherry-pick completes cleanly
+2. Creates regular PR (ready for review)
+3. PR is NOT in draft mode
+4. Maintainer can review and merge immediately
+```
+
+### When Cherry-pick Has Conflicts
+
+```
+1. Cherry-pick encounters conflicts
+2. Workflow commits the conflict markers:
+   <<<<<<< HEAD
+   [code from release branch]
+   =======
+   [code from master PR]
+   >>>>>>> commit-hash
+
+3. Creates DRAFT PR
+4. PR description indicates there were conflicts
+5. Manual resolution required:
+   a. git fetch origin
+   b. git checkout backport-1234-to-v0.20.x-branch
+   c. Resolve conflicts in affected files
+   d. git add <resolved-files>
+   e. git commit -m "Resolve backport conflicts"
+   f. git push origin backport-1234-to-v0.20.x-branch
+   g. Mark PR as "Ready for review" in GitHub UI
+6. Maintainer reviews and merges
+```
+
+### Conflict Resolution Best Practices
+
+- **Review the original PR**: Understand what changed
+- **Check the release branch**: Understand why conflicts occurred
+- **Test after resolving**: Run tests locally before pushing
+- **Update commit message**: Explain what conflicts were resolved and how
+- **Request review**: Don't merge without review, even after resolving conflicts
+
+## Multiple Backports
+
+You can backport to multiple release branches simultaneously by adding multiple labels.
+
+### Example: Backport to Two Branches
+
+```
+PR #1234 merged with labels:
+- backport-v0.20.x-branch
+- backport-v0.19.x-branch
+
+Workflow creates TWO backport PRs:
+
+PR #1235:
+  Title: [v0.20.x-branch] Backport #1234: Original title
+  Base: v0.20.x-branch
+  Labels: no-changelog
+
+PR #1236:
+  Title: [v0.19.x-branch] Backport #1234: Original title
+  Base: v0.19.x-branch
+  Labels: no-changelog
+```
+
+### Independent Processing
+
+Each backport is processed independently:
+
+- One backport may succeed while another has conflicts
+- One backport may fail validation while another succeeds
+- Each backport creates a separate branch and PR
+- Each backport PR is reviewed and merged independently
+
+### Example with Mixed Results
+
+```
+PR #1234 with labels:
+- backport-v0.20.x-branch  →  ✓ Clean cherry-pick, regular PR created
+- backport-v0.19.x-branch  →  ✗ Conflicts, draft PR created
+- backport-v0.99.x-branch  →  ✗ Branch doesn't exist, workflow fails
+```
+
+In this case:
+1. PR #1235 to v0.20.x-branch is ready for review
+2. PR #1236 to v0.19.x-branch needs conflict resolution
+3. No PR created for v0.99.x-branch (validation failed)
+4. Remove the incorrect label and add the correct one. The workflow will 
+   re-trigger when you add the new label.
+
+## Technical Details
+
+### Workflow File
+
+Location: `.github/workflows/backport.yml`
+
+### Trigger Events
+
+```yaml
+on:
+  pull_request_target:
+    types: [closed, labeled]
+```
+
+- **closed**: Triggers when PR is closed (checks if merged)
+- **labeled**: Triggers when any label is added
+
+### Permissions Required
+
+```yaml
+permissions:
+  contents: write        # Create branches and commits
+  pull-requests: write   # Create and manage PRs
+  issues: read          # Read PR metadata
+```
+
+### Workflow Condition
+
+```yaml
+if: |
+  github.event.pull_request.merged == true &&
+  contains(join(github.event.pull_request.labels.*.name, ','), 'backport-v')
+```
+
+Only runs when:
+1. PR is actually merged (not just closed)
+2. At least one label contains `backport-v`
+
+### Label Pattern
+
+```yaml
+label_pattern: '^backport-(v.+)$'
+```
+
+Regex explanation:
+- `^` - Start of string
+- `backport-` - Literal text
+- `(v.+)` - Capture group: "v" followed by one or more characters
+- `$` - End of string
+
+Examples:
+- `backport-v0.20.x-branch` → matches, captures `v0.20.x-branch`
+- `backport-v0.19.x-branch` → matches, captures `v0.19.x-branch`
+- `backport-candidate` → doesn't match (no "v" after dash)
+
+### Cherry-pick Strategy
+
+```yaml
+merge_commits: skip
+```
+
+- Uses `git cherry-pick` for clean history
+- Skips merge commits (only cherry-picks actual changes)
+- Preserves original commit messages and authorship
+- Maintains PGP signatures where present
+
+### Conflict Resolution Strategy
+
+```yaml
+experimental: |
+  conflict_resolution: draft_commit_conflicts
+```
+
+- Creates draft PR with conflict markers
+- Allows manual resolution
+- Preserves all context and metadata
+
+## Troubleshooting
+
+### Problem: Workflow Doesn't Trigger
+
+**Symptoms:**
+- Added `backport-v0.20.x-branch` label
+- No workflow run appears in Actions tab
+
+**Possible causes:**
+
+1. **Label format is wrong**
+   - ❌ `backport-0.20.x-branch` (missing "v")
+   - ✅ `backport-v0.20.x-branch`
+
+2. **PR is not merged**
+   - Workflow only runs on merged PRs
+   - Check PR status
+
+3. **Workflow is disabled**
+   - Check `.github/workflows/backport.yml` exists
+   - Check workflow is enabled in Settings → Actions
+
+### Problem: Workflow Fails with "Branch doesn't exist"
+
+**Error message:**
+```
+Error: Target branch 'v0.21.x-branch' does not exist (from label 'backport-v0.21.x-branch')
+Error: The following target branches do not exist: v0.21.x-branch
+Error: Please ensure the branch exists before adding the backport label
+```
+
+**Solution:**
+
+1. **Verify branch name:**
+   ```bash
+   git ls-remote --heads origin | grep v0.21
+   ```
+
+2. **Check available release branches:**
+   ```bash
+   git branch -r | grep origin/v0 | grep -v fork
+   ```
+
+3. **Fix the label:**
+   - Remove incorrect label
+   - Add correct label with existing branch name
+
+### Problem: Cherry-pick Has Conflicts
+
+**Symptoms:**
+- Backport PR created as DRAFT
+- PR description mentions conflicts
+- Branch has files with conflict markers
+
+**Solution:**
+
+1. **Fetch and checkout the branch:**
+   ```bash
+   git fetch origin
+   git checkout backport-1234-to-v0.20.x-branch
+   ```
+
+2. **Find conflicted files:**
+   ```bash
+   grep -r "<<<<<<< HEAD" .
+   ```
+
+3. **Resolve each conflict:**
+   - Open the file in an editor
+   - Review both versions:
+     ```
+     <<<<<<< HEAD
+     [Release branch version]
+     =======
+     [Master PR version]
+     >>>>>>> commit-hash
+     ```
+   - Choose the correct code or merge both
+   - Remove conflict markers
+
+4. **Commit the resolution:**
+   ```bash
+   git add <resolved-files>
+   git commit -m "Resolve backport conflicts for PR #1234
+
+   Conflicts occurred due to [explanation].
+   Resolution: [describe what you did]"
+   git push origin backport-1234-to-v0.20.x-branch
+   ```
+
+5. **Mark PR ready for review:**
+   - Go to PR on GitHub
+   - Click "Ready for review"
+
+### Problem: Multiple Labels but Only One Backport Created
+
+**Symptoms:**
+- Added `backport-v0.20.x-branch` and `backport-v0.19.x-branch`
+- Only one PR created
+
+**Possible causes:**
+
+1. **One label format is wrong**
+   - Check both labels start with `backport-v`
+   - Fix incorrect label, workflow will retry
+
+2. **One branch doesn't exist**
+   - Check workflow logs for validation errors
+   - Verify both branches exist
+
+3. **Workflow still running**
+   - Check Actions tab for in-progress runs
+   - Wait for workflow to complete
+
+### Problem: Backport PR Missing `no-changelog` Label
+
+**Symptoms:**
+- Backport PR created successfully
+- CI fails on changelog check
+
+**Solution:**
+
+1. **Manually add the label:**
+   - Add `no-changelog` label to the backport PR
+
+2. **Check workflow configuration:**
+   - Verify `.github/workflows/backport.yml` has:
+     ```yaml
+     labels: no-changelog
+     ```
+
+3. **Re-run the workflow:**
+   - Remove and re-add the backport label on original PR
+   - New backport PR will have correct label
+
+### Getting Help
+
+If you encounter issues not covered here:
+
+1. **Check workflow logs:**
+   - Go to Actions tab
+   - Click on the failed workflow run
+   - Review step-by-step logs
+
+2. **Check workflow file:**
+   - `.github/workflows/backport.yml`
+   - Verify configuration matches this documentation
+
+3. **Manual backport:**
+   - If automated backport fails repeatedly, you can backport manually:
+     ```bash
+     # Create branch from target release branch
+     git checkout v0.20.x-branch
+     git checkout -b manual-backport-123-to-v0.20.x
+
+     # Cherry-pick commits from the original PR
+     git cherry-pick <commit-hash>
+
+     # Resolve any conflicts, then:
+     git add .
+     git commit
+     git push origin manual-backport-123-to-v0.20.x
+
+     # Create PR targeting v0.20.x-branch with no-changelog label
+     gh pr create --base v0.20.x-branch --label no-changelog
+     ```
+
+4. **Report issues:**
+   - If you find a bug in the workflow
+   - Open an issue with workflow logs and details

+## Backporting Changes
+
+After a PR is merged to master, it may need to be backported to release branches
+(e.g., `v0.20.x-branch`) to include the fix or feature in upcoming patch releases.
