How Road to Kubernetes covers it

How deep it goes
Defines the trigger and demonstrates its placement in YAML, but defers other runner operating systems and advanced configuration.
Examples
Uses a Hello World workflow that checks out code and runs an echo command.
What it assumes
Assumes a GitHub repository and basic ability to create, commit, and push a workflow YAML file.
What you can do after
Operate/configure it via GitHub Actions by adding the trigger to YAML and launching the workflow from GitHub.com.
How it connects
Connects GitHub Actions workflows with YAML, push triggers, jobs, runners, and workflow steps.
