Make sure to get technical support. There is a chance you will need technicians or the ICT teacher or a colleague whose skills are sharper to help you with this. Basic practical necessities like the availability of computers and tablets for preparing and conducting game sessions can be difficult to maintain, but teachers need to be able to trust that the necessary technology is reliable and available and to make checklists of equipment, licences and software you will need. This is where the school needs to support teachers and they need to form teams.
