 Utility scripts for maintaining the beads project.
 
+## release.sh (⭐ The Easy Button)
+
+**One-command release** from version bump to local installation.
+
+### Usage
+
+```bash
+# Full release (does everything)
+./scripts/release.sh 0.9.3
+
+# Preview what would happen
+./scripts/release.sh 0.9.3 --dry-run
+```
+
+### What It Does
+
+This master script automates the **entire release process**:
+
+1. ✅ Kills running daemons (avoids version conflicts)
+2. ✅ Runs tests and linting
+3. ✅ Bumps version in all files
+4. ✅ Commits and pushes version bump
+5. ✅ Creates and pushes git tag
+6. ✅ Updates Homebrew formula
+7. ✅ Upgrades local brew installation
+8. ✅ Verifies everything works
+
+**After this script completes, your system is running the new version!**
+
+### Examples
+
+```bash
+# Release version 0.9.3
+./scripts/release.sh 0.9.3
+
+# Preview a release (no changes made)
+./scripts/release.sh 1.0.0 --dry-run
+```

+### Output
