+# Android Technical Information #
+Welcome to the Android technical documentation section of the site. Here you
+can find technical information useful to people and organizations who are
+looking to modify, contribute to, or port the Android software. This is "under
+the hood" information intended for engineers.
+
+## Dalvik Technical Information ##
+The Dalvik Virtual Machine is the heart of Android. It's a fast, just-in-time
+compiled, optimized bytecode virtual machine. Android applications are
+compiled to Dalvik bytecode and run on the Dalvik VM. This section includes
+detailed information such as the Dalvik bytecode format specification,
+design information on the VM itself, and so on.

+on the upstream bluez project. Android then layers various IPC and similar
+libraries to link the bluez library with the Android Bluetooth stack and API.

+
+
+## NFC Technical Information ##
+The Android Open-Source Project also includes an NFC implementation. Unlike
+the Android Bluetooth stack, much of the Android NFC stack is new code
+originally contributed to the Android Open-Source Project. This code links the
+Android NFC API to a device's NFC hardware. This section also includes
+information on related Android technologies, such as the simple NDEF Push
+Protocol.
