It looks like all I would have to do is attach an ethernet cable to one of the yellow connections, run it out to the garage & connect it to the green (WAN) connection of the second router?
But it also sounds like it could be a little tricky to get the two routers to link together, being that I'm new to all this WI-FI stuff & computers in general.
