 ## Introduction
-These are the step by step instructions on Cross-Compiling ArmNN under an x86_64 system to target an Arm64 system. This build flow has been tested with Ubuntu 16.04.
-The instructions show how to build the ArmNN core library and the Boost, Protobuf, Caffe, Tensorflow, Tflite, Flatbuffer and Compute Libraries necessary for compilation.

+#####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 Caffe and Tensorflow parsers in 21.02. This will be removed in 21.05.
