+Install with Helm
+------------------------------
+
+Copy the below commands, replacing the ``<YOUR_CLUSTER_NAME>`` placeholder.
+
+On some clusters this can take a while, so don't panic if it appears stuck:
+
+.. tab-set::
+
+    .. tab-item:: Normal Clusters
+        :name: install-standard
+
+        .. code-block:: bash

+
+    .. tab-item:: EKS
+        :name: install-eks
+
+        To use all Robusta features, ensure storage is enabled on your cluster. If necessary, refer to the EKS documentation and install the `EBS CSI add-on <https://docs.aws.amazon.com/eks/latest/userguide/managing-ebs-csi.html#adding-ebs-csi-eks-add-on>`_
+
+        .. details:: How do I know if my cluster has storage enabled?
+
+            Try installing Robusta. If storage is not configured, you'll receive an error:
+
+            .. code-block::
+
+                PreBind plugin "VolumeBinding": binding volumes: timed out waiting for the condition
+
+            Running ``kubectl get pvc -A`` will also show PersistentVolumeClaims in ``Pending`` state.
+
+            In this case, follow the instructions above and enable storage for your cluster.
+
+        .. code-block:: bash

+
+    .. tab-item:: GKE Autopilot
+        :name: install-gke-autopilot
+
+        Due to Autopilot restrictions, some components are disabled for Robusta's bundled Prometheus. Don't worry, everything will still work.

+
+    .. tab-item:: Local/Test Cluster
+        :name: install-test-clusters
+
+        Test clusters tend to have fewer resources. To lower Robusta's resource requests, set ``isSmallCluster=true``.
