quick tip: i can recommend github actions for super simple setup

github actions (in its beta) may need to be enabled/signed up per repo or for the entire organization (@supercollider). very easy to set up, you get a new "actions" tab on the repo where all builds will show up. make a new file .github/workflows/main.yml containing your commands/scripts.
