How to Use and Create Actions (Marketplace)

What is an Action?

Actions are the building blocks that power your workflow. A workflow can contain one or more actions, either as individual steps or as part of an action group. An action is a reusable unit of code that can be used in multiple workflows. You can create your own actions, use actions created by the GitHub community, or use a combination of both.
