+Building aubio for Android
+--------------------------
+
+To compile aubio for android, you will need to get the `Android Native
+Development Toolkit (NDK) <https://developer.android.com/ndk/>`_, prepare a
+standalone toolchain, and tell waf to use the NDK toolchain. An example script
+to complete these tasks is available in ``scripts/build_android``.
