Before booking this course, kindly ensure that your child has an official Minecraft License (Java Edition) that works on Windows PC, Apple Mac or Linux PC. Note that Minecraft accounts for Xbox, Pocket Edition or any other platforms are not compatible with this course. If you are unsure as to whether you already own a Minecraft license, one way to tell is if your child has a Minecraft username that they use to log in to play Minecraft on Windows PC, Apple Mac or Linux PC.  If your child does not have a Minecraft License (Java Edition), you can purchase one from the official Mojang website.
