GitHub Actions are workflows that are triggered by events, comprising a sequence of actions which run in containers with the ability to use environment variables and secrets. They support both curated community actions and official GitHub actions, allowing developers to think globally while acting locally in their workflow development. Resources for further exploration include demos and blogs on creating and using GitHub Actions.
