Users can immediately install with: `brew install sbryngelson/mfc/mfc` +3. Add installation instructions to MFC README +4. Monitor usage for a few weeks + +**Then submit Option 2 (homebrew-core):** + +1. Once tap is proven stable, submit to homebrew-core +2. After merge, users can use simpler: `brew install mfc` +3.
