Choosing what your workflow does

Use workflows to run multiple jobs.

Actions are the building blocks that power your workflow. A workflow can contain actions created by the community, or you can create your own actions directly within your application's repository. This guide will show you how to discover, use, and customize actions.

You can script with GitHub CLI in GitHub Actions workflows.

You can use workflow commands when running shell commands in a workflow or in an action's code.

You can use GitHub Actions workflows to run scripts.

Modify the default permissions granted to GITHUB_TOKEN.

You can evaluate expressions in workflows and actions.

GitHub sets default variables for each GitHub Actions workflow run. You can also set custom variables for use in a single workflow or multiple workflows.

You can access context information in workflows and actions.

You can define outputs to pass information from one job to another.

Define the default settings that will apply to all jobs in the workflow, or all steps in a job.

Specify a deployment environment in your workflow.

Run a single job at a time.

Create a matrix to define variations for each job.

To make your workflows faster and more efficient, you can create and use caches for dependencies and other commonly reused files.

Artifacts allow you to share data between jobs in a workflow and store data once that workflow has completed.
