Unguided trek in the Markha Valley: what accommodation options are there?

Hi there. I’d like to know about accommodation options for unguided hikers. I see there are campsites—are the tents already set up, or do we need to bring our own? Same question for sleeping bags—ours are a bit tight, I think (comfort temp 0°C). Are blankets provided? I’m picturing a camp where everything’s taken care of, including meals, but I’m worried I might be mistaken... Thanks in advance
