+2.3 On Android
+--------------
+
+Prerequisites:
+
+- Android Studio
+- From Android Studio's package manager you need to install `NDK` and `CMake`
+
+Android builds work a bit differently from Linux and Windows. You are required to generate a gradle project per build
+target. For example, if you want to generate a project for the `Sponza` sample just type from a Linux terminal:
+
+	$cd path/to/anki
+	$./Samples/Sponza/GenerateAndroidProject.sh
+
+or from a PowerShell terminal on Windows:
+
+	$cd path/to/anki
+	$./Samples/Sponza/GenerateAndroidProject.bat
+
+The `GenerateAndroidProject` scripts will generate a project in the root directory of AnKi. So for the `Sponza` sample
+the script will create a directory named `AndroidProject_Sponza`.
+
+Then you can open the `AndroidProject_Sponza` project from `Android Studio` and build it, debug it, run it etc.
