@majcher Starting from scratch with role-playing games, it is not D&D, but you can look at Fate https://fate-srd.com/ . Download the Fate Accelerated version and it will cover the basics.

RPGs are collaborative games, so you will need a few fellow players. You could try looking for a local game shop, or convention, and join a game there

If you really want just D&D, then pick up the Starter Set, which has already created characters and all the basics.
