Hi 91jordy, and welcome to Chordie!
Reading and writing Tab is not that difficult and really is used as a substitute for those of us who don't read standard music notation as well as we'd like. This link might help you in your quest for more information:

Welcome back to the guitar after your hiatus of five years and I hope you persist through the discomfort of those first few bleeding fingers! Visit Chordie often, ask questions, post comments and make yourself at home here among this global community of guitar (and other stringed instrument) players.
Friendships are forged with a simple hello..... Hello!
Have fun with your music... it just keeps getting better.
Take Care; Doug
