+7) GETTING THE GAMEDATA, RUNNING THE GAME
+__________________________________________
+
+To play the game, you need the game data from a legal copy of the game, which 
+unfortunately requires Steam for Windows - Steam for Linux or OSX won't do, because
+(at least currently) the Doom3 BFG game is only installable on Steam for Windows.
+Even the DVD version of Doom3 BFG only contains encrytped data that is decoded
+by Steam on install.
+
+Fortunately, you can run Steam in Wine to install Doom3 BFG and afterwards copy the 
+game data somewhere else to use it with native executables.
+Winetricks ( http://winetricks.org/ ) makes installing Windows Steam on Linux really easy.
+
+Anyway:
+
+1. Install Doom3 BFG in Steam (Windows version), make sure it's getting 
+   updated/patched.
+
+2. Create your own doom3bfg directory, e.g. /path/to/Doom3BFG/
+
+3. Copy the game-data's base dir from Steam to that directory 
+   (e.g. /path/to/Doom3BFG/), it's in
+	/your/path/to/Steam/steamapps/common/DOOM 3 BFG Edition/base/
+
+4. Copy your RBDoom3BFG executable that you created in 5) or 6) to your own 
+   doom3bfg directory (/path/to/Doom3BFG).
+   
+   Your own doom3bfg directory now should look like:
+	/path/to/Doom3BFG/
+	 ->	RBDoom3BFG (or RBDoom3BFG.exe on Windows)
+	 ->	base/
+		 ->	classicmusic/
+		 ->	_common.crc
+		 ->	(etc)
+
+5. Run the game by executing the RBDoom3BFG executable.
+
+6. Enjoy
