I've recently had occasion to do a fair amount of work with Go modules and vendoring, and I've had trouble finding simple how-tos for doing some (to me) basic things. It turns out they aren't that complicated, but they do involve multiple systems working together which may not be obvious to Go newbies (like me!). I'm writing this down both for my own reference and in the hopes that maybe it will help someone else get started with this stuff. I make no promises as to the accuracy of these steps, but they did what I needed.
