-1. Prepare the VM/machine you want to add to your cluster by following the steps outlined in [Plan and prepare your Service Fabric cluster deployment](service-fabric-cluster-creation-for-windows-server.md)

+When using certificates to secure the cluster they are expected to be installed in the local certificate stores in preparation for the node to join the cluster. The analog is applicable when using other forms of security.

 3. Remote desktop (RDP) into the VM/machine that you want to add to the cluster
 4. Copy or [download the standalone package for Service Fabric for Windows Server](https://go.microsoft.com/fwlink/?LinkId=730690) to the VM/machine and unzip the package
 5. Run Powershell with elevated privileges, and navigate to the location of the unzipped package
-6. Run the *AddNode.ps1* script with the parameters describing the new node to add. The example below adds a new node called VM5, with type NodeType0 and IP address 182.17.34.52, into UD1 and fd:/dc1/r0. The *ExistingClusterConnectionEndPoint* is a connection endpoint for a node already in the existing cluster, which can be the IP address of *any* node in the cluster. The cluster certificate used below should be installed under Personal (My) store of the current user.
