 ### Pre-requisites
 
 1. A GitHub repo containing a directory with your Helm charts (eg: `/charts`)
-1. A GitHub project [Secret](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets#creating-encrypted-secrets) named `CR_TOKEN` with the value of a GitHub [personal access token](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line#creating-a-token)
-    * The token must have `repo` scope
-    * The token's user must have write access to the project
-    * To mitigate risk you may wish to limit the token to a single project by creating a [machine user](https://developer.github.com/v3/guides/managing-deploy-keys/#machine-users)
-    * Please note the personal access token is required because of an [Actions bug](https://github.community/t5/GitHub-Actions/Github-action-not-triggering-gh-pages-upon-push/m-p/31266/highlight/true#M743), and will hopefully be unnecessary in the future
 1. Create a workflow `.yml` file in your `.github/workflows` directory. An [example workflow](#example-workflow) is available below.
