 ## Source Code
 
 Longhorn is 100% open source software. Project source code is spread across a number of repos:
 
 1. Longhorn Engine -- Core controller/replica logic https://github.com/longhorn/longhorn-engine
 2. Longhorn Instance Manager -- Controller/replica instance lifecycle management https://github.com/longhorn/longhorn-instance-manager
-3. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
+3. Longhorn Share Manager -- NFS provisioner that exposes Longhorn volumes as ReadWriteMany volumes. https://github.com/longhorn/longhorn-share-manager
+4. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
 4. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui
 
 ## Prerequisites
 
-1. Rancher v2.1+
-2. Docker v1.13+
-3. Kubernetes v1.14+
-4. Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
-5. Make sure `open-iscsi` has been installed in all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains `open-iscsi` already.
-
-## Uninstallation
-
-1. To prevent damage to the Kubernetes cluster, we recommend deleting all Kubernetes workloads using Longhorn volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc).
+1. Docker v1.13+
+2. Kubernetes v1.16+
+3. Make sure `curl`, `findmnt`, `grep`, `awk` and `blkid` has been installed in all nodes of the Kubernetes cluster.
+4. Make sure `open-iscsi` has been installed in all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains `open-iscsi` already.
 
-2. From Rancher UI, navigate to `Catalog Apps` tab and delete Longhorn app.
+## Installation
+1. Add Longhorn chart repository.
+```
+helm repo add longhorn https://charts.longhorn.io
+```
 
-## Troubleshooting
+2. Update local Longhorn chart information from chart repository.
+```
+helm repo update
+```
 
-### I deleted the Longhorn App from Rancher UI instead of following the uninstallation procedure
+3. Install Longhorn chart.
+- With Helm 2, the following command will create the `longhorn-system` namespace and install the Longhorn chart together.
+```
+helm install longhorn/longhorn --name longhorn --namespace longhorn-system
+``` 
+- With Helm 3, the following commands will create the `longhorn-system` namespace first, then install the Longhorn chart.
 
-Redeploy the (same version) Longhorn App. Follow the uninstallation procedure above.
+```
+kubectl create namespace longhorn-system
+helm install longhorn longhorn/longhorn --namespace longhorn-system
+```
 
-### Problems with CRDs
+## Uninstallation
 
-If your CRD instances or the CRDs themselves can't be deleted for whatever reason, run the commands below to clean up. Caution: this will wipe all Longhorn state!
+With Helm 2 to uninstall Longhorn.
+```
+helm delete longhorn --purge
+```
 
+With Helm 3 to uninstall Longhorn.
 ```
-# Delete CRD instances and definitions
-curl -s https://raw.githubusercontent.com/longhorn/longhorn/v0.8.1/scripts/cleanup.sh |bash -s v062
-curl -s https://raw.githubusercontent.com/longhorn/longhorn/v0.8.1/scripts/cleanup.sh |bash -s v070
+helm uninstall longhorn -n longhorn-system
+kubectl delete namespace longhorn-system
 ```
