Yes, you're fairly accurate. It means cafes, non-essential retail stores, restaurants, etc. should shut down. People should only venture outside for groceries, medicine, or if their work demands it. Work that is non-essential should be put on hold. No non-essential travel, no going out for dinner, no casual shopping for goods, no hanging out or drinking with friends or family.

Stay at home as often as you can, reasonably. You don't need a curfew, yet!
