+# Kubeflow Pipelines Helm Chart
+
+## Known Differences vs Kustomize (platform-agnostic)
+
+This chart aims for functional parity with the Kustomize deployment in
+`manifests/kustomize/env/platform-agnostic`. Some differences are intentional
+due to Helm subcharts and install semantics:
+
+- Argo Workflows is installed via the `argo-workflows` subchart. Resource names
+  and some RBAC object names differ from the Kustomize namespace-install
+  manifests, even when `singleNamespace` is enabled.
+- Argo Workflows CRDs are disabled in values, but Helm can still install CRDs
+  from other sources; Kustomize applies CRDs separately outside the
+  platform-agnostic overlay.
+- MySQL is deployed via the Bitnami `mysql` subchart, which uses a StatefulSet,
+  headless service, and additional resources (PDB, NetworkPolicy, Secret) that
+  do not exist in the Kustomize deployment (which uses a simple Deployment + PVC).
+- KFP CRDs in `charts/kubeflow-pipelines/crds` are installed by Helm, while the
+  Kustomize platform-agnostic overlay does not include them by default.
+
+If you need exact 1:1 resource parity with Kustomize, replace the Argo and MySQL
+subcharts with Kustomize-equivalent native templates.
+
+## Compatibility Options
+
+To reduce naming drift without removing subcharts, this chart provides optional
+compatibility resources (enabled by default):
+
+- `compat.argo.rbac`: Adds `argo-role` and `argo-binding` to match the
+  namespace-install RBAC objects from Kustomize.
+- `compat.argo.priorityClass`: Adds `PriorityClass` `workflow-controller`.
+- `compat.mysql.pvc`: Creates `PersistentVolumeClaim` `mysql-pv-claim` and sets
+  MySQL to use it via `mysql.primary.persistence.existingClaim`.
+- `compat.mysql.deployment`: Creates a Kustomize-style MySQL `Deployment` and
+  `ServiceAccount`/`Service`. This is only rendered when `mysql.enabled=false`
+  to avoid running two MySQL workloads.
+
+These are intended to close parity gaps in tooling and tests that expect
+Kustomize resource names.
