🔵 1. Event Happens (Trigger)

GitHub Actions start when something happens in your repository.
These are called Triggers.

✨ Examples of triggers:

• 👨‍💻 push (code pushed to repo)

• 🔀 pull_request opened

• ⏳ schedule (run everyday at 8 PM)

• 🖱️ workflow_dispatch (manual run)

This is like hitting the “Start Button” 🎬 in your automation pipeline.

🟣 2. Workflow File (The Brain)

Inside .github/workflows/ you write a .yml file.
This file tells GitHub:

• What should trigger the workflow

• What jobs to run

• What steps inside each job

Think of it like a recipe card 📜 telling GitHub what to cook.

🟡 3. Runner Starts (The Worker Machine)

A runner is a machine (Linux/Windows/macOS) that executes your tasks.

GitHub gives you free runners like:

• 🐧 Ubuntu

• 🪟 Windows

• 🍎 macOS

It’s like a robot worker 🤖 assigned to execute your workflow.

🟢 4. Jobs → Steps → Actions

A workflow contains jobs, and each job has steps.

🧩 Steps can be:

• Commands (like npm install, python3 script.py)

• Pre-built Actions (marketplace reusable components)

• Custom actions you create

Think of it like:
Jobs = Tasks
Steps = Instructions
Actions = Ready-made mini-tools 🧰

🔴 5. Actions Marketplace (Superpowers Store)

GitHub provides thousands of plug-and-play actions like:

• 🚀 Deploy to AWS

• 🔧 Lint your code

• 📦 Build Docker images

• 🧪 Run unit tests

• 🔔 Send notifications

You don’t need to write everything from scratch — just plug and use.

🟠 6. Output & Status

When the workflow executes, GitHub shows:

• 🟢 Success

• 🔴 Failure

• 🟡 In-progress

You can also see logs, artifacts, and debugging info.
