 MacOS currently does not have any packages. We are still working on setting up MacOS packaging. Meanwhile, you can [build](https://github.com/PolyMC/PolyMC/blob/develop/BUILD.md#macos) it for yourself.
 
+## Development Builds
+
+There are per-commit development builds available [here](https://github.com/PolyMC/PolyMC/actions). These have debug information in the binaries, so their file sizes are relatively larger.
+Builds are provided for Linux, AppImage on Linux, Windows, and macOS.
