          **macOS**
          1. Open `Amplitron-macOS.dmg`, drag Amplitron to Applications
          2. **First launch**: Right-click the app → **Open** → click **Open** in the dialog
          3. Or run: `xattr -cr /Applications/Amplitron.app` then open normally

          **Linux**
          1. Extract the archive: `tar -xzf Amplitron-Linux-x64.tar.gz`
          2. Run: `cd Amplitron-Linux && ./amplitron.sh`

          > ⚠️ **Note**: Windows SmartScreen and macOS Gatekeeper warnings appear because the app is not yet code-signed with a paid certificate. The app is fully open-source — verify the code on GitHub.
