Report bugs
If something breaks, open an issue on GitHub. Include your distribution, whether you're on Wayland or X11, and the steps to reproduce.
Build and test
The most useful thing right now is to run the pre-release build and tell us what's broken. The download page has the commands.
Send patches
Pull requests are welcome on the Regulus repository. If you're planning something large, open an issue first so we can talk it through.
Spread the word
If Regulus is useful to you, a star on GitHub helps other people find it.
