A Quick Guide to GitHub Actions

⚡ GitHub Actions is a powerful CI/CD tool built right into GitHub. Here’s what I’ve learned from setting up my first few workflows.

The basics: A workflow is defined in a .yml file under .github/workflows/. It runs on “triggers” like push, schedule (cron), or workflow_dispatch (manual trigger).

Key concepts:

• Jobs — Independent units of work that run in parallel by default
• Steps — Sequential commands within a job
• Actions — Reusable building blocks (e.g., actions/checkout@v4)
• Secrets — Encrypted variables for API keys and tokens

💡 Pro tip: Use workflow_dispatch to test your workflows manually before relying on scheduled runs.
