Learn continuous integration and delivery with GitHub Actions, the automation built into GitHub. Write workflows that run your tests on every pull request, build on many versions at once, cache dependencies, keep secrets safe, publish Docker images and deploy to production. Every example is a workflow you can edit and run in the page against a pretend repository, with logs that look just like GitHub's.
