 It is easy to miss steps when going through the ROS 2 installation tutorial. If you run into errors in the next few steps, a good place to start is to go back and make sure you have installed ROS 2 correctly.  One that users commonly forget is to source the ROS 2 install itself.  ::
 
-  source /opt/ros/humble/setup.bash
+  source /opt/ros/{DISTRO}/setup.bash
 
 .. note:: Unlike ROS 1 setup scripts, in ROS 2 the setup scripts do not attempt to switch what version of ROS you are using.  This means that if you have previously sourced a different version of ROS, including from within your ``.bashrc`` file, you will run into errors during the building step.  To fix this change what is sourced in your ``.bashrc`` and start a new terminal.
