-The generic_x86 board target provides basic services on very basic

-need an appropriate kernel for your emulation (or device).
+The "generic_x86" product defines a non-hardware-specific IA target
+without a kernel or bootloader.
 
-A1. Create a new top level directory and pull the AOSP repository
-        mkdir $HOME/AOSP
-        cd $HOME/AOSP
-        repo init -u git://android.git.kernel.org/platform/manifest.git
-        repo sync
+It can be used to build the entire user-level system, and
+will work with the IA version of the emulator,
 
-A2. Copy in the kernel
-        cd $HOME/AOSP
-        cp ~/bzImage.your_device $HOME/AOSP/prebuilt/android-x86/kernel/kernel
-
-A3. Build
-        cd $HOME/AOSP
-        source build/envsetup.sh
-        lunch generic_x86-eng
-        make -j8
-
-The build will generate some image files whose format may or may not be correct for your
-device. You can build an installer image disk for the VirtualBox emulator using the command:
-
-A4. Build a VirtualBox installer image
-	cd $HOME/AOSP
-        source build/envsetup.sh
-        lunch generic_x86-eng
-        make -j8 installer_vdi

+The "vbox_x86" product defines a non-hardware-specific target intended
+to run on the VirtualBox emulator.
+
+Most of the Android devices (networking, phones, sound, etc) do not work.
+
+ADB via ethernet works with this target. You can use 'adb install' to
+test applications that do not require network, phone or sound support.
+This emulation is useful because VirtualBox runs much faster then does the
+QEMU emulators (at least until a KVM enabled QEMU emulator is available).
