+Build
-===========
+=====
+
+Supported build platforms are Linux, FreeBSD and Windows (via Cygwin). Due to
+customized linker scripts, simulator support is currently limited to x86 and
+x86_64 archs. Following dependencies have to be met:
 
-Zunaechst muessen alle Abhaenigkeiten installiert sein. Unter Debian/Ubuntu Systemen

+Package names are based on those packages found in the Debian/Ubuntu
+repositories. Please adapt the names according to your Linux distribution (or
+FreeBSD for that matter).

+
+Configure
+---------
+
+Open a terminal and type:
  > make menuconfig
 
-konfiguriert, und mit 
+This brings up a curses based text interface for configuring certain aspects of
+your target platform. Be careful if you use a full-fledged IDE like Eclipse to
+manage the build, as integrated terminal emulators tend to choke on curses
+generated shell output. Just ensure that 'make menuconfig' has been run at least
+once in an ordinary terminal emulator after a fresh checkout or after issuing
+'make mrproper'.
+
+Compile
+-------
 
+To build for the actual target platform, just type:
  > make 
 
-gebaut werden.
+If you want to test and debug your code within a GUI applications, you can use
+the simulator:
+ > make simulator
 
+Please keep in mind that the simulator is NOT an emulator. All it does is to
+compile the Borgware 2D to an ordinary host application so you can step
+through your C-Code. The GUI application scans the simulated frame buffer every
+40ms and draws its contents.
