GitHub Actions

INTRODUCTION​

GitHub Actions helps you automate your software development workflows from within GitHub. You can deploy workflows in the same place where you store code and collaborate on pull requests and issues. In GitHub Actions, a workflow is an automated process that you set up in your GitHub repository. You can build, test, package, release, or deploy any project on GitHub with a workflow. Each workflow is made up of individual actions that run after a specific event (like a pull request) occur. The individual actions are packaged scripts that automate software development tasks.
