No worries! Have you worked on car brakes before? Bike brakes aren't any more "black magic" than those, though again I will say they're more fiddly in my experience, because getting all the air bubbles out can be a pain sometimes. I've bled countless car brakes and it was always fairly easy with a helper to pump the pedal, but my experience with my 2 bikes has been more troublesome. I'm not sure what the problem is, considering cars have rather complex systems with multiple master cylinder reservoirs (2, for redundancy), 180 or 360-degree bends in the brakes lines, and now ABS systems, but getting all the air bubbles out of my bike systems turned out to be a bit of a black art, and it differs by caliper position (front vs rear) and hardware mfgr. The $20 brake bleed kits on Amazon are pretty good though, including all the stuff you'll need.

The nice thing about hydraulics is that, once they're set up, they're good until you need to change the pads usually, and even then the fluid is probably fine unless it's old. Rim brakes, on the other hand, need constant adjustment and fiddling just to keep them from rubbing, as the pads wear. I don't miss them one bit.
