 3. To create an account, simply enter the details you wish to use at the login screen then click Log In. Do *not* click register, as this will just lead to a blank screen.
 4. Make a new character, and enjoy the game! Your progress will be saved automatically, and you can resume playing by entering the login details you used in step 3.

 ## Gameplay
 
 The goal of the project is to faithfully recreate the game as it was at the time of the targeted build.
-While most features are implemented and the game is playable start to finish, there may be missing functionality or bugs present.
+The server is not yet complete, however, and some functionality is still missing.
 
-Depending on the server configuration, you'll have access to certain commands.
+Because the server is still in development, ordinary players are allowed access to a few admin commands:
 
-For the public servers: Original has item spawning, the ability to set player speed/jump height, and teleportation enabled (default account level 50).
-Meanwhile the Academy server is more meant for legitimate playthroughs (default account level 99).
+![](res/sane_upsell.png)
 
-When hosting a local server, you will have access to all commands by default (account level 1).
+### Movement commands
+* A `/speed` of around 2400 or 3000 is nice.
+* A `/jump` of about 50 will send you soaring
+* [This map](res/dong_number_map.png) (credit to Danny O) is useful for `/warp` coordinates.
+* `/goto` is useful for more precise teleportation (ie. for getting into Infected Zones, etc.).
 
-For a list of available commands, see [this wiki page](https://github.com/OpenFusionProject/OpenFusion/wiki/Ingame-Command-list).
+### Item commands
