+- GUI to select which build to play
+- Auto-detection of Among Us install directory
+- Auto-launch of BetterCrewLink if installed
+
+# Contributing
+
+Help. I have no standards. Just look at the code.
+
+## How to Build
+
+- [Install Rust](https://www.rust-lang.org/learn/get-started)
+- Download repository
