 ##Building Native Android Libraries
 To build using the Android NDK toolchain, placed in the downloaded NDK is a script file, for Mac OS X, named `ndk-build` or, for Windows Desktop, named `ndk-build.cmd.` When Android Studio is used to download and install the NDK, by default, the NDK is installed directly under the Android SDK root folder. Also, by default, the NDK root folder is named "ndk-bundle."

 > Due to the knife-edge roll of NDK version 11 by developers.android.com, it's recommended that ARToolKit Android developers download, install and use NDK version 11 or greater. Not doing so can result in link incompatibilities between your native libraries and their dependency on ARToolKit prebuilt native libraries. 
 
 The next step after installing the Android SDK and NDK is to set some environment variables (recommended for both Mac OS X and Windows Desktop development environments). For Windows Desktop, the following can be defined as Windows system environment variables or exported by the Git bash shell's ".bash_profile" startup file.

 To build the Android Studio example app projects that do include native C/C++ source code and to build the project's C/C++ source, after executing the "./build" script file, execute "./build_native_examples.sh", without arguments. When "build_native_examples.sh" script completes without errors, the native Android Studio example projects are populated with the content of the generated *libs* folder. Using an actual example Android Studio project, "ARSimpleNativeProj," the *libs* folder is copied here:
 
-<div style="margin-left: 2em;">
-<p>&lt;ARTK SDK or repo root&gt;/<br/>
-AndroidStudioProjects/ARSimpleNativeProj/aRSimpleNative/src/main/
-</p>
-</div>
+```
+<ARTK SDK or repo root>/AndroidStudioProjects/ARSimpleNativeProj/aRSimpleNative/src/main/
+```
 
 Once the native dependencies are built and copied, open an Android Studio example project and build the project's Java source files. If all builds, deploy to an Android simulated device or a *real* development device. Note: the camera doesn't work on simulated devices so it's best to test with *real* devices.
 
 To use the native ARToolKit binaries in your own Android application, you will need to copy the *libs* folder generated by the "build.sh" script to your Android application project folder using the following project offset:
 
-<p style="margin-left: 2em;">
- &lt;Android Studio Project&gt;/&lt;module&gt;/src/main
