            | Platform | File |
            |----------|------|
            | Windows (x86_64) | `ironpad-windows-x86_64-${{ github.ref_name }}.zip` |
            | macOS (x86_64) | `ironpad-macos-x86_64-${{ github.ref_name }}.tar.gz` |
            | Linux (x86_64) | `ironpad-linux-x86_64-${{ github.ref_name }}.tar.gz` |

            **Linux:** Extract the tar.gz and run `./ironpad`. Works on any distro -- it's a standalone binary with no dependencies.

            **macOS:** Extract and run. You may need to allow it in System Settings > Privacy & Security on first launch.

            **Windows:** Extract the zip and run `ironpad.exe`.
