 ## Introduction
 These are step by step instructions for using the Android NDK to build Arm NN.
 They have been tested on a clean install of Ubuntu 16.04, and should also work with other OS versions.
-The instructions show how to build the Arm NN core library and the optional TensorFlow parser.
+The instructions show how to build the Arm NN core library.
+Building protobuf is optional. We have given steps should the user wish to build it (i.e. as an Onnx dependency).
 All downloaded or generated files will be saved inside the `~/armnn-devenv` directory.
 
-#####Note: We are currently in the process of removing boost as a dependency to Arm NN. This process is finished for everything apart from our unit tests. This means you don't need boost to build and use Arm NN but you need it to execute our unit tests. Boost will soon be removed from Arm NN entirely. We also are deprecating support for Tensorflow parsers in 21.02. This will be removed in 21.05.
