 Corps are an important part of the game, so joining one early might be a good idea.

+## Logging off
+
+It might be tempting just to leave your character wherever you are and log off, but it is probably a bad idea.
+When you log off, NPCs and players who can attack you when you are logged on can still attack you while logged
+off. You will fight back, but never flee or heal yourself - so logging off in the wrong place could leave you
+dead and waiting to re-clone (with less XP) when you log back in.
+
+Instead, pick a safe place to log off. If you are broke, you could try the Homeless Shelter (HS) in
+Melbs Central. Fog machines mean no one can fight there - but you also can't keep any stuff you can't
+carry there, so it is more a home of last resort.
+
+For nicer digs, try heading a bit further south along King Street to Condos on King (CK). There, you can rent
+a studio apartment (`rent studio`) for a daily fee, and ask the robot to guide you to your apartment any time
+you want to visit with `in yourusername`. You have your own personal doorstep, but keep in mind that the
+doorstep itself is accessible to anyone who wants to go there. Head further east to go into your private
+apartment itself.
+
+It comes with a door, but it is up to you to buy a lock if you want security (without a lock, anyone you have
+allowed to visit, or are at war with, can come in, and help themselves to your stuff - and attack you if you
+are at war). Keep in mind that if you are at war and have allowed pick, locks can be picked though!
+
+To buy a lock, head to McKillock's Security (MS). Once you have the lock, go in to the room you want to lock
+(you have to install it from the inside, not from the doorstep), and install it with a command like
+`install scanlock on door to west`. You can uninstall it if you want to change to a different lock later:
+`uninstall scalock from door to west`.
+
+The door will open for you if you try to go through it, but no one else will be able to open it without
+picking it first (and if you haven't issued an `allow combat` command including `allow pick`, you are completely
+safe while the door is closed and it's just you in there. Keep in mind that if you open the door, others can
+get through too until you close it. So if you come out of your apartment, remember to `close east` before moving
+on!
+
+Congratulations on taking the first step on your property journey - enjoy your new home! Feel free to invite
+others in with `allow visit from <user>` - set a limit like `until 5 minutes`, or `disallow visit from <user>`
+after if you don't want them coming back. Be careful about inviting dishonest visitors though in case they try
+to clean you out!
