Introduce yourself to the coaches one-by-one at the pre-event (if there is one), or at the very beginning of the workshop (as everyone is still arriving), to make sure they know they can turn to you with questions. This is also a good time to ask whether there were any technical issues with the installation. Some problems that appear minor during the installation can cause major issues later on, which might mean having to repeat a large part of the tutorial to fix them, potentially re-installing python, virtualenv, django, etc. (other minor problems stay minor, so in many cases small deviations from the tutorial's installation steps are fine).
