 This [GitHub action](https://github.com/features/actions) will handle the  deploy process of your project to [GitHub Pages](https://pages.github.com/). It can be configured to upload your production-ready code into any branch you'd like, including `gh-pages` and `docs`.
 
 ## Getting Started :airplane:
-You can include the action in your workflow to trigger on any event that [GitHub actions supports](https://help.github.com/en/articles/events-that-trigger-workflows). If the remote branch that you wish to deploy to doesn't already exist the action will create it for you. Your workflow will also need to include the `actions/checkout` step before this workflow runs in order for the deployment to work.

 ## Configuration 📁
 
 The `with` portion of the workflow **must** be configured before the action will work. You can add these in the `with` section found in the examples above. Any `secrets` must be referenced using the bracket syntax and stored in the GitHub repositories `Settings/Secrets` menu. You can learn more about setting environment variables with GitHub actions [here](https://help.github.com/en/articles/workflow-syntax-for-github-actions#jobsjob_idstepsenv).
