+The server version can successfully be built.
+Some stuff are not working as intended, such as Actor or Vehicle. These systems are both almost fully implemented, but not really in stable state.
 
-- Actor
-- Vehicle
+Overall the server part and the game module are almost fully implemented, but the stability may vary, there may be some minor bugs and crashes.
 
 ### Client
 
-There is currently no client build because the UI code is currently unimplemented. Here is what's missing or unimplemented :
+The client version of OpenMoHAA is partially implemented and not stable currently. The cgame module is partially implemented as well, but is compatible with the original MOH:AA game. Credits to **Heavy Metal: F.A.K.K. 2**'s SDK for the cgame module.
