+# Release Process Documentation
+
+## Overview
+
+This document describes the automated release process for `azure/webapps-deploy` GitHub Action.
+
+---
+
+## Branch Structure
+
+| Branch | Purpose | Notes |
+|--------|---------|-------|
+| `master` | Active development | - |
+| `releases/v3` | v3.x releases | Synced with `master` via cherry-pick |
+| `releases/v2` | v2.x releases | Same codebase structure, some files have different logic |
+
+> **Note:** `releases/v2` and `releases/v3` share the same codebase structure. Only a few major files have different implementations. The release process is identical for both.
+
+---
+
+## How Users Consume This Action
+
+```yaml
+# Users reference major version tag
+- uses: Azure/webapps-deploy@v3   # Gets latest v3.x.x
+- uses: Azure/webapps-deploy@v2   # Gets latest v2.x.x
+```
+
+---
+
+## Release Workflow
+
+### Step 1: Prepare Changes
+
+**For v3 releases:**
+1. Develop feature on feature branch
+2. Merge PR to `master`
+3. Create a feature branch from `releases/v3`:
+   ```bash
+   git checkout releases/v3
+   git pull origin releases/v3
+   git checkout -b feature/my-feature-v3
+   ```
+4. Cherry-pick commits from `master`:
+   ```bash
+   git cherry-pick <commit-hash>
+   ```
+5. Push and create PR to `releases/v3`:
+   ```bash
+   git push origin feature/my-feature-v3
+   ```
+6. Get PR reviewed and merge to `releases/v3`
+
+**For v2 releases:**
+1. Develop feature on feature branch
+2. Merge PR to `master`
+3. Create a feature branch from `releases/v2`:
+   ```bash
+   git checkout releases/v2
+   git pull origin releases/v2
+   git checkout -b feature/my-feature-v2
+   ```
+4. Cherry-pick commits from `master`:
+   ```bash
+   git cherry-pick <commit-hash>
+   ```
+5. Push and create PR to `releases/v2`:
+   ```bash
+   git push origin feature/my-feature-v2
+   ```
+6. Get PR reviewed and merge to `releases/v2`
+
+> **Note:** Using feature branches allows for code review before changes land in release branches.
+
+---
+
+### Step 2: Create Release
+
+1. Go to **GitHub → Releases → Create a new release**
+2. Click **Choose a tag** → Type new tag (e.g., `v3.2.1`)
+3. Select **Target branch**: Choose the corresponding release branch
+   - `v3.x.x` → `releases/v3`
+   - `v2.x.x` → `releases/v2`
+4. Add release notes
+5. Click **Publish release**
+
+---
+
+### Step 3: Two-Stage Approval & Release
+
+When release is published, the workflow has **two approval stages**:
+
+**Stage 1: Minor Tag (`release-minor` environment)**
+1. Workflow shows changes in summary
+2. Approver reviews and approves
+3. Builds code and creates minor tag (e.g., `v3.2.1`)
+4. Users can test with `Azure/webapps-deploy@v3.2.1`
+
+**Stage 2: Major Tag (`release-major` environment)**
+1. After testing minor tag, approver approves
+2. Updates major tag (`v3`) to point to minor (`v3.2.1`)
+3. Users on `Azure/webapps-deploy@v3` now get the new version
+
+### One-time Setup
+
+Go to **repo Settings → Environments** and create two environments:
+
+1. **`release-minor`** - Required reviewers → Add your team
+2. **`release-major`** - Required reviewers → Add your team
+
+---
+
+## What's Different from Before
+
+| Aspect | Old Process | New Process |
+|--------|-------------|-------------|
+| `node_modules` | Committed to branch | ❌ Not needed (bundled with `ncc`) |
+| Build artifacts | In release branch | In tag only (`dist/index.js`) |
+| PR review | PR to releases/vX with node_modules | Review via workflow summary |
+| Manual steps | npm install, npm build, push | Automated |
+| Version tracking | Not tracked | Embedded in user agent |
+
+---
+
+## Rollback Procedure
+
+### Quick Rollback (move v3 tag back)
+
+```bash
+# Point v3 back to previous version
+git tag -fa v3 v3.2.0 -m "Rollback to v3.2.0"
+git push origin v3 --force
+```
+
+### Hotfix Release
+
+1. Fix the bug in `releases/v3` branch
+2. Create new release `v3.2.2`
+3. Workflow auto-updates `v3` tag
+
+---
+
+## Tag Naming Convention
+
+| Tag | Description |
+|-----|-------------|
+| `v3.2.1` | Specific release version |
+| `v3` | Always points to latest v3.x.x |
+| `v2.1.5` | Specific v2 release |
+| `v2` | Always points to latest v2.x.x |
+
+---
+
+
+## User Agent Tracking
+
+API calls now include version information:
+
+```
+GITHUBACTIONS_DeployWebAppToAzure_v3.2.1_<repo_hash>
+```
+
+This helps track which release version is being used.
+
+---
+
+## Security
+
+- Tag names are validated against pattern: `^v[0-9]+\.[0-9]+\.[0-9]+$`
+- Only maintainers can create releases
+- No secrets are exposed in the workflow
+
+---
+
+## Quick Reference
+
+### Create a release (same for v2 and v3)
+```
+1. Create feature branch from releases/vX
+2. Cherry-pick changes from master
+3. Create PR to releases/vX → Review → Merge
+4. Create release with tag vX.x.x → Publish
+5. Approve Stage 1 (release-minor) → Creates v3.2.1
+6. Test v3.2.1 if needed
+7. Approve Stage 2 (release-major) → Updates v3
+8. Done!
+```
