History of GitHub Actions
Introduction
GitHub Actions is a powerful feature of GitHub that allows developers to automate workflows directly within their repositories. It was introduced to streamline Continuous Integration (CI) and Continuous Deployment (CD) processes, enabling teams to build, test, and deploy their code more efficiently.

Key Concepts
Understanding GitHub Actions involves grasping several key components:
- Workflows: Automated processes defined in YAML files.
- Jobs: A set of steps that execute on the same runner.
- Steps: Individual tasks within a job, which can run commands or actions.
- Actions: Reusable code blocks that can be shared and used in workflows.
Best Practices
