 ### <a name="helm-charts"></a> Helm Charts
-To simplify the deployment, the Operator can be installed using a Helm chart (note only Helm v3 is supported). A Helm chart repository is maintained at the following URL: https://nvidia.github.io/gpu-operator (which in turn is maintained at the corresponding ‘gh-pages’ directory under https://github.com/NVIDIA/gpu-operator/tree/gh-pages)
+To simplify the deployment, the Operator can be installed using a Helm chart (note only Helm v3 is supported). The documentation for helm installation

 Continuous (‘nightly’) releases of the operator are available. Release milestones are available under ‘stable’.
