 5. Run './gradlew installDebug' in the project directory. This compiles the .java, creates an .apk with the native code embedded, and installs it on any connected Android device
 
+
+If you already have a project that uses CMake, the instructions change somewhat:
+
+1. Do points 1 and 2 from the instruction above. 
+2. Edit "<project>/app/build.gradle" to comment out or remove sections containing ndk-build
+   and uncomment the cmake sections. Add arguments to the CMake invocation as needed.
+3. Edit "<project>/app/jni/CMakeLists.txt" to include your project (it defaults to
+   adding the "src" subdirectory). Note that you'll have SDL2, SDL2main and SDL2-static
+   as targets in your project, so you should have "target_link_libraries(yourgame SDL2 SDL2main)"
+   in your CMakeLists.txt file. Also be aware that you should use add_library() instead of
+   add_executable() for the target containing your "main" function.
+
+If you wish to use Android Studio, you can skip the last step.

+4. Run './gradlew installDebug' in the project directory. It will build and install your .apk on any
