If you want a digital version of the basic rules, here is a good place to start. It contains all the basic rules for each base class, the rules regarding ability scores, actions and other general stuff, as well as a single subclass for each class. If you want more subclass options you'll have to buy a copy of the official books (players handbook, Xanathar's guide to everything, or Tasha's Cauldron of everything have the majority of the extra subclasses in them) or persuade a friend to share them with you.
