The entire game is up to read for free here: Book The book recommends players reading the Playing tab in order to familiarize themselves with the game.
In addition to the book I have here: DW Printouts including all the character classes and a list of the moves you can make for the game. You will need to look over this and print a copy of the first 2 pages that list the moves as well as the page containing your character sheet.
This fan made guide does a great job explaining the game: Dungeon World Guide
