Can anyone tell me a thing or two about technical writing?

Every winter I take on a big indoorsy project. Last winter it was making a quilt, the year before it was learning how to cook.

My project for this winter is to learn about technical writing. I’m probably going to start at the library and take a community college course on it later. I’ve been reading up on it a bit, and it sounds like my wheelhouse. You need to write clearly, know certain software programs, and make complex ideas easy to understand.

At this point, I’m basically doing it just for funsies. But out of curiosity, how is the job outlook in this field? And is there anything specific I should know?
