-## Accessing Phoscon ui
-deCONZ should now be available at http://ip.address.of.your.IOTstack.pc.here:8090/
+## Pre-installation
+Before running the command that creates the deconz Docker container (`docker-compose up -d`), you may need to add your Linux user to the dialout group, which allows the user access to serial devices (i.e. Conbee/Conbee II/RaspBee):
+
+`sudo usermod -a -G dialout pi` (pi user being used as an example)
+
+## Accessing the Phoscon UI
+The Phoscon UI is available using port 8090 (http://your.local.ip.address:8090/)
 
 ## Viewing the deCONZ Zigbee mesh
 The Zigbee mesh can be viewed using VNC (port 5901). The default VNC password is "changeme".
 
 ## Connecting deCONZ and Node-RED
-1) Install [node-red-contrib-deconz](https://flows.nodered.org/node/node-red-contrib-deconz) via the manage palette menu (if not already pre-installed with Node-RED)
-2) Open a deCONZ in node, select "Add new deconz-server" and type in the IP-address of your IOTstack pc (Rpi) and type in port 8090 (not websocket port)
-3) Open deCONZ (http://ip.address.of.your.IOTstack.pc.here:8090/) and open settings>gateway>advanced. Click "Authenticate app".
-4) Go back to your Node-RED instance and click the magick:get setting button in the server node. The API and websocket port will be automatically inserted. Click "Add" and you are good to go.
