+## Release Instructions
+
+1. Create a release prep branch
+
+2. Update the version number in chart/Chart.yaml
+
+3. Do a `helm unittest -u chart` and then run precommit to
+   regenerate the helmdocs.  Inspect the diff and make sure
+   the only changes are the Chart version
+
+4. Update the chart version number in the example
+   of `helm repo search` in the main README.md
+
+5. Submit & merge a PR with these changes
+
+6. Manually trigger the `Release Charts` workflow in the Actions
+   tab of the MLBatch GitHub project.  This action will automatically
+   generate and push tags for the newly released chart and trigger an
+   update of the GH Pages (which contains the helm repo).
