Welcome to the Prism Launcher repository! 🌈
We just set some things up for you. To get building, you can run:
```
$ cd "$cmakeBuildDir"
$ ninjaBuildPhase
$ ninjaInstallPhase
```
Feel free to ask any questions in our Discord server or Matrix space:
- https://prismlauncher.org/discord
- https://matrix.to/#/#prismlauncher:matrix.org
And thanks for helping out :)
