GitHub Actions

ELI5 — The Vibe Check

GitHub Actions is CI/CD built right into GitHub. Push code, run tests, deploy — all from YAML files in your repo. No separate CI server needed. It's like having a robot butler inside your repository that does whatever you ask when stuff happens.

Real Talk

GitHub Actions is a CI/CD and automation platform integrated into GitHub. Workflows are defined in YAML under .github/workflows/ and triggered by events (push, PR, schedule, webhook). Supports matrix builds, reusable workflows, composite actions, and a marketplace of community actions.
