+# Automated Release Process - Quick Start Guide
+
+This repository now has a **fully automated GitHub release process** with multiple options for triggering releases.
+
+## 🚀 Three Ways to Release
+
+### Option 1: Push Button Release (Recommended for Quick Releases)
+
+**Perfect when:** You've already committed version changes and want to release with one click.
+
+1. Update `Cargo.toml` version and `CHANGELOG.md`
+2. Commit and push to main
+3. Go to **Actions** → **Create Release** → **Run workflow** button
+4. Enter version (e.g., `0.2.9`) and click "Run workflow"
+5. Done! 🎉
+
+The workflow will automatically:
+- Create the git tag
+- Run tests
+- Create GitHub Release with changelog
+- Publish to crates.io
+- Build example binaries for Linux/macOS/Windows
+
+### Option 2: Use the Version Bump Script (Recommended for Developers)
+
+**Perfect when:** You want automation to help with version management.
+
+```bash
+# Bump version (patch: 0.2.8 → 0.2.9)
+./bump-version.sh patch
+
+# Update CHANGELOG.md with your changes
+# (The script creates a new section for you)
+
+# Commit and push
+git add Cargo.toml CHANGELOG.md
+git commit -m "Bump version to 0.2.9"
+git push origin main
+
+# Create and push tag
+git tag v0.2.9
+git push origin v0.2.9
+```
+
+### Option 3: Traditional Tag-Based (Classic Approach)
+
+**Perfect when:** You prefer the traditional git workflow.
+
+```bash
+# Update Cargo.toml and CHANGELOG.md manually
+# Commit and push
+git add Cargo.toml CHANGELOG.md
+git commit -m "Bump version to 0.2.9"
+git push origin main
+
+# Create and push tag
+git tag v0.2.9
+git push origin v0.2.9
+```
+
+## 📋 What You Get
+
+Every release automatically includes:
+
+✅ **GitHub Release** with formatted release notes from CHANGELOG.md  
+✅ **crates.io Publication** for Rust users  
+✅ **Example Binaries** for Linux, macOS, and Windows  
+✅ **Automated Testing** before release  
+✅ **Version Validation** to catch mistakes  
+
+## 📁 Files Added
+
+- **`.github/workflows/release.yml`** - Main release automation workflow
+- **`CHANGELOG.md`** - Track changes between versions
+- **`bump-version.sh`** - Helper script for version management
+- **`RELEASING.md`** - Comprehensive release documentation
+
+## 🔧 Setup Required
+
+Only one setup step is needed:
+
+1. Ensure `CRATES_IO_TOKEN` secret is configured in repository settings
+   - Go to Settings → Secrets and variables → Actions
+   - Should already exist if you've published before
+
+## 🎯 Next Steps
+
+**For your next release:**
+
+1. Choose your preferred method above
+2. Update CHANGELOG.md with changes
+3. Follow the steps for your chosen method
+4. Monitor Actions tab to watch the automation
+
+**Questions?**
+
+- See detailed docs: `RELEASING.md`
+- Check workflow definition: `.github/workflows/release.yml`
+- Run version script help: `./bump-version.sh`
+
