Github Actions Workflow

This is your go-to for spinning up GitHub Actions workflows without memorizing YAML syntax every time. It covers the full spectrum: CI/CD pipelines, matrix testing across Node versions, Docker builds with layer caching, and automated releases. The reference guides give you complete working examples instead of snippets, which is honestly the right approach since Actions workflows are useless when half-done. Pay attention to the security practices here, especially around handling secrets in pull requests from forks, because that's where people usually shoot themselves in the foot. Good for both setting up new repos and modernizing crusty Jenkins pipelines.
