-### Add More Processing Nodes
+### Manage Processing Nodes
 
 WebODM can be linked to one or more processing nodes running [NodeODM](https://github.com/OpenDroneMap/NodeODM). The default configuration already includes a "node-odm-1" processing node which runs on the same machine as WebODM, just to help you get started. As you become more familiar with WebODM, you might want to install processing nodes on separate machines.

 You **will not be able to distribute a single job across multiple processing nodes**. We are actively working to bring this feature to reality, but we're not there yet. 
 
+If you don't need the default "node-odm-1" node, simply pass the `--no-default-node` flag when starting WebODM:
+
+`./webodm.sh restart --no-default-node`. 
+
+Then from the web interface simply manually remove the "node-odm-1" node.
+
 ### Enable SSL
 
 WebODM has the ability to automatically request and install a SSL certificate via [Let’s Encrypt](https://letsencrypt.org/), or you can manually specify your own key/certificate pair.
