Ask HN: First time working from home; what to do or not do?

I'll be working as a full-stack developer part-time for the next few months from home. It's a small team of about three or four devs that I've worked with before. It's a really nice company and I'm looking forward to going back to work for them. However, I'll be working from home for the vast majority of the foreseeable future, and this is my first time working from home. Any advice on what I can do (or not do) to maximize productivity, reduce distraction, and facilitate teamwork?
