GitHub Actions is a Continuous Integration and Continuous Delivery (CI/CD) platform that allows developers to automate processes such as building, testing and deploying pipelines. GitHub Actions is a workflow automation service.
GitHub Actions also helps automate Code and Repository Management. It is a powerful service that can be leveraged to automate code reviews or issue management among other repo centric activities.
It can also automate deployment tasks like publishing documentation, building and deploying packages or containers and running code quality checks and tests.
