 # CSQC, MENUQC, SVQC and GAMEQC blocks
 
+Xonotic uses the ***csprogs.dat*** from the server you're playing on, as it must match the server's ***progs.dat*** code (whereas your ***menu.dat*** is always your local copy).

 Menu and HUD code are actually separated as they run in 2 distinct programs: ***csprogs.dat*** and ***menu.dat***
 
 Server program is ***progs.dat***
