-Set a password for the VNC Server:
+`sudo raspi-config`
-sudo vncpasswd -service
+
+In the menu, go to

+
+
+After the Raspiblitz is rebooted, set a password for the VNC Server:  
+`sudo vncpasswd -service`  
+
 Set the Authentication parameter:  
-sudo echo "Authentication=VncAuth" > /etc/vnc/config.d/common.custom
+`sudo echo "Authentication=VncAuth" > /etc/vnc/config.d/common.custom`  
-Restart the VNC Server for settings to take effect
+
-sudo systemctl restart vncserver-x11-serviced
+Restart the VNC Server for settings to take effect:  
+`sudo systemctl restart vncserver-x11-serviced`  
+
 Open the relevant port in the firewall (ufw):  
-sudo ufw allow vnc
+`sudo ufw allow vnc`
 
-Note: You may have to set the resolution through raspi-config in certain situations:
+Start the VNC server from the Raspiblitz:  
-sudo raspi-config > Advance Options > Resolution
+`vncserver`  
+This will run by default in the display number '1'. If you want to specify another number, run this (change  *\<display-number\>* to whatever you prefer):  
+`vncserver :<display-number>`  
 
-Hint: From macOS, there is a built in VNC client hidden away at: /System/Library/CoreServices/Applications/Screen\ Sharing.app
+![VNC server started](pictures/vnc-server-started.png)  
+
+From the VNC client (e.g. your PC, laptop), connect to the IP that the previous command has displayed in the screen (I covered it in pink in the screenshot). If everything is alright, you can see the display from the VNC client now.
+
+In order to stop broadcasting your display, stop the server from the Raspiblitz with this:  
+`vncserver -kill :<display-number>`  
+
+For example:
+`vncserver -kill :1`  
+
+
+**Note**: You may have to set the resolution through raspi-config in certain situations:  
+`sudo raspi-config`  
+ *Advanced Options > Resolution*
