 This tutorial uses an Aarch64 machine with Ubuntu 18.04 installed that can build all components
 natively (no cross-compilation required). This is to keep this guide simple.

+@section delegateintro About the delegate
+'armnnDelegate' is a library for accelerating certain TensorFlow Lite (TfLite) operators on Arm hardware. It can be
+integrated in TfLite using its delegation mechanism. TfLite will then delegate the execution of operators supported by
+Arm NN to Arm NN.
+
+The main difference to our @ref S6_tf_lite_parser is the amount of operators you can run with it. If none of the active
+backends support an operation in your model you won't be able to execute it with our parser. In contrast to that, TfLite
+only delegates operations to the armnnDelegate if it does support them and otherwise executes them itself. In other
+words, every TfLite model can be executed and every operation in your model that we can accelerate will be accelerated.
+That is the reason why the armnnDelegate is our recommended way to accelerate TfLite models.
+
+If you need help building the armnnDelegate, please take a look at our [build guide](delegate/BuildGuideNative.md).
+An example how to setup TfLite to integrate the armnnDelegate can be found in this
+guide: [Integrate the delegate into python](delegate/IntegrateDelegateIntoPython.md)

+
+Arm NN is written using portable C++14 and the build system uses [CMake](https://cmake.org/), therefore it is possible
+to build for a wide variety of target platforms, from a wide variety of host environments.
+
+Arm NN is managed by a single CMake project. That allows you to build multiple tools at once by combining the CMake
+options from different build guides.
