Play dnd - how?

can't find people nearby? loads of groups play online now, voice chat plus a virtual tabletop, and a fair few of them advertise specifically for total beginners. try a one-shot first - a single session game - before you sign up to a campaign that runs for months.

nothing to reinstall, it's a tabletop game. you want four or five people with one of them running it, and the basic rules are free to read. don't build a character from scratch for a first session - take a pregenerated one, play a short starter adventure, see whether you enjoy it. dice or a dice app, either is fine. honestly the rules are the easy part, finding the group is the bit that takes months.
