# Gitea Actions is a CI/CD service for the Gitea source code server, meaning it
# allows us to run code operations (such as testing or deploys) when our git
# repositories are updated. Any machine can act as a Gitea Action Runner, so
# the Runners don't necessarily need to be running Gitea. All we need is an API
# key for Gitea to connect to it and register ourselves as a Runner.
