 ## Adding new projects
 
-This repo uses GNU `date` and `sed` which is installed with `brew install gnu-sed coreutils` on Mac OS.
+Upstream repositories publish their charts via automation using something like the [stefanprodan/helm-gh-pages](https://github.com/stefanprodan/helm-gh-pages) action.
 
-To create a helm chart release run:
-
-```
-./prepare-artifacts.sh /path/to/chart-dir
-```
-
-Where `chart-dir`, is a local directory containing the helm chart you wish to package.
-
-Then commit your changes and submit a PR to the [`gh-pages`](https://github.com/equinixmetal-helm/charts/tree/gh-pages) branch.
-
-Some upstream repositories publish their charts via automation. You do not need to use the above script unless manually generating the chart.
