+Uninstalling K3s may cause data loss!
 :::
 
 If you installed K3s using the installation script, a script to uninstall K3s was generated during installation.
 
+Running the uninstall script stops K3s and all running pods, and deletes the local cluster datastore, [Local Storage](../storage.md#setting-up-the-local-storage-provider) Persistent Volume data, node configuration, and all of the scripts and CLI tools.
+It does not remove any data from external datastores, or created by pods using external Kubernetes Persistent Volumes.

 If you are planning on rejoining a node to an existing cluster after uninstalling and reinstalling, be sure to delete the node from the cluster to ensure that the node password secret is removed. See the [Node Registration](../architecture.md#how-agent-node-registration-works) documentation for more information.
