-With no added options, `./setup.sh` will compile and bundle [Proton](https://github.com/CachyOS/proton-cachyos) + [protonfixes](https://github.com/Open-Wine-Components/umu-protonfixes) + [umu-run](https://github.com/Open-Wine-Components/umu-launcher) together into a redistributable `$pkgname.tar.xz`, along with installing to `$HOME/.steam/root/compatibilitytools.d/$buildname` (`umu-run` is excluded from the Steam installation).

 # Credit
 Of course, none of this would be possible without the teams behind Proton and Wine, but I'd like to give special credit to:
-- [loathingKernel](https://github.com/loathingKernel) for putting together the [version](https://github.com/CachyOS/proton-cachyos) of Proton that this build script uses
+- [loathingKernel](https://github.com/loathingKernel) for help with all things related to Proton, umu-launcher, and build scripts
+- [MarshNello](https://github.com/NelloKudo/osu-winello) for making it easy to use this package for playing osu! with just a couple commands
 - The team behind [Open-Wine-Components](https://github.com/Open-Wine-Components/) for making using Proton outside of Steam as easy as this
