 * Linux Instance
   - Use a SSH client to connect to the instance.
-  - Once you are logged to a terminal, use ~/start.sh to start Selenium and VNC servers. On the main machine, this will also mount the mathjaxtest bucket on ~/MathJax-results/ and start the task handler.
+  - Use the "screen" command to handle several windows. Quick guide to the screen environment: use "Ctrl + a, Ctrl + c" to create a new window, "Ctrl + a, Ctrl + n" to move to the next window, "Ctrl + a, Ctrl + p" to move to the previous window, use the "exit" command to close the current window and finally "Ctrl + a, Ctrl + d" to detach the screen session. When you detach a screen session, all the servers will keep running even if you logout from the SSH session. You can restore your screen session when you connect again with the command "screen -r" (provided the machine has not been stopped since your last connection).
+  - In one screen window, use "~/start.sh" to start the VNC server. On the machine 10.0.0.30, this will also mount the mathjaxtest bucket on ~/MathJax-results/ and start the task handler.
   - If necessary, you may use a VNC client to connect to the instance.
 
 * Windows Instance
   - Use a RDP client to connect to the instance.
   - Open a Windows Session.
-  - Open a command line and execute "java -jar selenium-server.jar" to run the Selenium Server.
