Replying to How did you learn how do use your DSLR's?

I'm using a canon vixia hf s100 right now. And it's not cutting it. So I'm going to upgrade soon and get a DSLR. But while I'm in the long process of saving up, I thought I should get to know a little bit how to use them first. Right now I've been messing around with my dad's Sony ax-300 but I want a little bit of a guidance. Does anyone have any guides I could go to or anything to learn more and familiarize myself with DSLR's? Thanks for the help.
