First I have to Sign Up for a GitHub account.
Then I have to Create a repo to run Actions.
Try out the features of GitHub Actions in 5 minutes or less in the Quickstart for GitHub Actions.
GitHub has a nice UI for monitoring and troubleshooting. You can view the status and results of each step in your workflow, debug a failed workflow, search and download logs, and view billable job execution minutes.
Encrypted Secrets allow you to store sensitive information in your organization, repository, or repository environments. There are secrets at both the organization and repository. You can even create enviornment secrets.
You can use Actions from the GitHub Marketplace. Use the millions of open source libraries available on GitHub to create your own actions. Write them in JavaScript or create a container action—both can interact with the full GitHub API and any other public API.
