Introduction

You only need a GitHub repository to create and run a GitHub Actions workflow.

The following example shows you how GitHub Actions jobs can be automatically triggered, where they run, and how they can interact with the code in your repository.

Creating your workflow

Create a .github/workflows directory in your repository on GitHub if this directory does not already exist.

In the .github/workflows directory, create a file named like github-actions.yml.

Example Start YAML file:

The double curly braces are missing for the GitHub action, don’t forget to put them back.
