-$ build/gyp_v8 -D target_arch=x64

+This will build makefiles for ia32, x64 and the ARM simulator with names
+Makefile-ia32, Makefile-x64 and Makefile-armu respectively.
 
-To generate Makefiles and build for the arm simulator on Linux:
----------------------------------------------------------------
+To build and run for ia32 in debug and release version do:
 
-$ build/gyp_v8 -I build/armu.gypi
-$ make BUILDTYPE=Debug
+$ make -f Makefile-ia32
 $ out/Debug/shell
-$ make BUILDTYPE=Release
+$ make -f Makefile-ia32 BUILDTYPE=Release

+Change the makefile to build and run for the other architectures.
