Setting up runner for Gitea Actions

My simple Hello World repo is at jhsu802701/hello-world-bash - hello-world-bash - Gitea: Git with a cup of tea

Gitea Actions tries to get going but never does. The actions page shows that test.yaml is flagged with the message “No matching online runner with label: ubuntu-latest”.

My list of runners shows that I have no runners available. The instructions to be geared for a self-hosted Gitea setup, which I’m not currently using.

So exactly what do I need to do to get GitHub actions to do what it’s supposed to do? Exactly how do I provide the necessary runner? In GitHub workflows, just providing the .github/workflows/*.yml file would be enough.
