What are GitHub Actions?

Definition and explanation of GitHub Actions CI/CD platform.

Definition

GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform integrated directly into GitHub. It allows developers to automate workflows such as building, testing, and deploying code right from their repository.

How it works

Workflows are defined in YAML files and execute on virtual machines (runners) hosted by GitHub or on self-hosted runners. They are triggered by GitHub events like pushes, pull requests, or issue creations.
