 +=== Last adjustments ===
  
 +There are two versions of CRAM available in the VM. By default, the setup is designed to connect and work with a project from the Unreal Engine, for intricate physics simulation. We don't need any of that for the upcoming tutorials, instead we change to the stable, standalone version of CRAM. In the VM, launch a terminal with Ctrl-Alt-T and open up the file ''.bashrc''.
 +
 +<code>
 +nano .bashrc
 +</code>
 +
 +Put a ''#'' symbol in front of the ''source'' command for day 1 & 2 of the FallSchool, and remove it from the line below, referring to day 3 of the FallSchool. Save and close the file and type ''source .bashrc'' to activate the changes in your current terminal. From now on the changes are applied on every newly opened terminal.
 +
 +By doing so, the terminal uses a different ROS workspace. Sourcing a ROS workspace enables the terminal session to access everything from that workspace, like loading a programming environment, or changing a namespace.
