Hi, just downloaded the client but now I don't know what to do next. The site saids I've to edit the realmlist.wtf file but in win10, after the whole archive has been unzipped, I can't open that kind of file. Next to that, what do I have to do? Sorry for the dumb questions but I was expecting a readme file with a bunch of instructions also when it comes to informatics I'm literally the worst. Thanks in advance!
