Starter workflows

If you create a new action through the Actions tab, you’ll see this Jekyll action there. You might have to click the more… button.

That action references jekyll.yml in the actions/starter-workflows repo.

That unfortunately does’t provide any info though on what you do after a successful build in terms of publishing and viewing results.

This Action was not used for this site and is not covered in more detail.
