+### Publishing helm charts on registry.k8s.io
+
+Helm charts are a popular way to install Kubernetes applications.
+Publishing a helm chart in the Kubernetes organization follows a similar process
+as publishing an image.
+
+1. The subproject should build, document, and support the helm chart development.
+2. The subproject should push the chart to the staging docker repo.
+3. On release tags, one can promote the chart and images to registry.k8s.io by obtaining the sha 
+   for the tagged helm chart and the tagged image.
+4. Open a PR into your images directory (registry.k8s.io/images/k8s-staging-SUBPROJECT/images.yaml)
+5. Add chart and image sha to the respective sections.
+6. Once PR is merged, confirm both images and helm charts exist by `helm install subproject oci://registry.k8s.io/charts/subproject --version=$VERSION`

+Charts are published in the same location as the images.
