The CI job definitions for sourcehut are a pleasure to use: https://man.sr.ht/builds.sr.ht/manifest.md

A really neat feature is that you can also trigger a job by just submitting a yaml file (with the web interface, the API or the cli) without needing to push a commit for each job. This is neat for infrequent tasks, or for testing CI manifests before committing them.
