I did some android app - there is plenty - that teaches you rules, moves, basic tactics. Once you grasp it, you can easily start playing.

Online-go.com is compatible with other clients on OGS servers and pairs you with players on your level, you can play quick games or correspondence, you don't really have to commit that much time.

Then some Youtube, chatting with friends...

That's how I did it, I believe @saunter similar
