+## Introduction
 These are step by step instructions for using the Android NDK to build ArmNN.
 They have been tested on a clean install of Ubuntu 18.04, and should also work with other OS versions.
 The instructions show how to build the ArmNN core library and the optional TensorFlow parser.
 All downloaded or generated files will be saved inside the `~/armnn-devenv` directory.
 
-#### <a name="downloadNDK">Download the Android NDK and make a standalone toolchain</a>
+## Download the Android NDK and make a standalone toolchain
 
 * Download the Android NDK from [the official website](https://developer.android.com/ndk/downloads/index.html):
-
-     ```bash
-     mkdir -p ~/armnn-devenv/toolchains
-     cd ~/armnn-devenv/toolchains
-     # For Mac OS, change the NDK download link accordingly.
-     wget https://dl.google.com/android/repository/android-ndk-r20b-linux-x86_64.zip
-     unzip android-ndk-r20b-linux-x86_64.zip
-     export NDK=~/armnn-devenv/android-ndk-r20b
-     export NDK_TOOLCHAIN_ROOT=$NDK/toolchains/llvm/prebuilt/linux-x86_64
-     export PATH=$NDK_TOOLCHAIN_ROOT/bin/:$PATH
-     ```
-
-	 You may want to append the above export variables commands to your `~/.bashrc` (or `~/.bash_profile` in Mac OS).
+ ```bash
+ mkdir -p ~/armnn-devenv/toolchains
+ cd ~/armnn-devenv/toolchains
+ # For Mac OS, change the NDK download link accordingly.
+ wget https://dl.google.com/android/repository/android-ndk-r20b-linux-x86_64.zip
+ unzip android-ndk-r20b-linux-x86_64.zip
+ export NDK=~/armnn-devenv/android-ndk-r20b
+ export NDK_TOOLCHAIN_ROOT=$NDK/toolchains/llvm/prebuilt/linux-x86_64
+ export PATH=$NDK_TOOLCHAIN_ROOT/bin/:$PATH
+
+ # You may want to append the above export variables commands to your `~/.bashrc` (or `~/.bash_profile` in Mac OS).
+ ```
 
 * With the android ndk-20b, you don't need to use the make_standalone_toolchain script to create a toolchain for a specific version of android. Android's current preference is for you to just specify the architecture and operating system while setting the compiler and just use the ndk directory.
 
-#### <a name="buildBoost">Build the Boost C++ libraries</a>
+## Build the Boost C++ libraries
 
 * Download Boost version 1.64:
-
-   ```bash
-   mkdir ~/armnn-devenv/boost
-   cd ~/armnn-devenv/boost
-   wget https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.bz2
-   tar xvf boost_1_64_0.tar.bz2
-   ```
+```bash
+mkdir ~/armnn-devenv/boost
+cd ~/armnn-devenv/boost
+wget https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.bz2
+tar xvf boost_1_64_0.tar.bz2
+```
 
 * Build:
 
 	(Requires clang if not previously installed: `sudo apt-get install clang`)

-     toolset=clang-arm link=static cxxflags=-fPIC \
-	 --with-test --with-log --with-program_options -j16
-    ```
- Note: You can specify the 'Android_API' version you want. For example, if your ANDROID_API is 27 then the compiler will be aarch64-linux-android27-clang++.

+## 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.
 
-#### <a name="installCCT">Cross-compiling ToolChain</a>
+## Cross-compiling ToolChain
 * Install the standard cross-compilation libraries for arm64:
-    ```
-    sudo apt install crossbuild-essential-arm64
-    ```
+```
+sudo apt install crossbuild-essential-arm64
+```
 
-#### <a name="buildProtobuf">Build and install Google's Protobuf library</a>
+## Build and install Google's Protobuf library
 
-## We support protobuf version 3.12.0
+We support protobuf version 3.12.0
 * Get protobuf from here: https://github.com/protocolbuffers/protobuf : 
-    ```bash
-    git clone -b v3.12.0 https://github.com/google/protobuf.git protobuf
-    cd protobuf
-    git submodule update --init --recursive
-    ./autogen
-    ```
+```bash
+git clone -b v3.12.0 https://github.com/google/protobuf.git protobuf
+cd protobuf
+git submodule update --init --recursive
+./autogen
+```
 * Build a native (x86_64) version of the protobuf libraries and compiler (protoc):
   (Requires cUrl, autoconf, llibtool, and other build dependencies if not previously installed: sudo apt install curl autoconf libtool build-essential g++)
-    ```
-    mkdir x86_64_build
-    cd x86_64_build
-    ../configure --prefix=$HOME/armnn-devenv/google/x86_64_pb_install
-    make install -j16
-    cd ..
-    ```
+```
+mkdir x86_64_build
+cd x86_64_build
+../configure --prefix=$HOME/armnn-devenv/google/x86_64_pb_install
+make install -j16
+cd ..
+```
 * Build the arm64 version of the protobuf libraries:
-    ```
-    mkdir arm64_build
-    cd arm64_build
-    export CC=aarch64-linux-gnu-gcc \
-    export CXX=aarch64-linux-gnu-g++ \
-    ../configure --host=aarch64-linux \
-    --prefix=$HOME/armnn-devenv/google/arm64_pb_install \
-    --with-protoc=$HOME/armnn-devenv/google/x86_64_pb_install/bin/protoc
-    make install -j16
-    cd ..
-    ```
-
-#### <a name="buildCaffe">Build Caffe for x86_64</a>
+```
+mkdir arm64_build
+cd arm64_build
+export CC=aarch64-linux-gnu-gcc \
+export CXX=aarch64-linux-gnu-g++ \
+../configure --host=aarch64-linux \
+--prefix=$HOME/armnn-devenv/google/arm64_pb_install \
+--with-protoc=$HOME/armnn-devenv/google/x86_64_pb_install/bin/protoc
+make install -j16
+cd ..
+```
+
+## Build Caffe for x86_64
 * Ubuntu 16.04 installation. These steps are taken from the full Caffe installation documentation at: http://caffe.berkeleyvision.org/install_apt.html
 * Install dependencies:
-    ```bash
-    sudo apt-get install libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev
-    sudo apt-get install --no-install-recommends libboost-all-dev
-    sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev
-    sudo apt-get install libopenblas-dev
-    sudo apt-get install libatlas-base-dev
-    ```
+```bash
+sudo apt-get install libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev
+sudo apt-get install --no-install-recommends libboost-all-dev
+sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev
+sudo apt-get install libopenblas-dev
+sudo apt-get install libatlas-base-dev
+```
 * Download Caffe from: https://github.com/BVLC/caffe. We have tested using tag 1.0
-    ```bash
-    git clone https://github.com/BVLC/caffe.git
-    cd caffe
-    git checkout eeebdab16155d34ff8f5f42137da7df4d1c7eab0
-    cp Makefile.config.example Makefile.config
-    ```
+```bash
+git clone https://github.com/BVLC/caffe.git
+cd caffe
+git checkout eeebdab16155d34ff8f5f42137da7df4d1c7eab0
+cp Makefile.config.example Makefile.config
+```
 * Adjust Makefile.config as necessary for your environment, for example:
-    ```
-    #CPU only version:
-    CPU_ONLY := 1
-
-    #Add hdf5 and protobuf include and library directories (Replace $HOME with explicit /home/username dir):
-    INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/ $HOME/armnn-devenv/google/x86_64_pb_install/include/
-    LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/ $HOME/armnn-devenv/google/x86_64_pb_install/lib/
-    ```
+```
+#CPU only version:
+CPU_ONLY := 1
+
+#Add hdf5 and protobuf include and library directories (Replace $HOME with explicit /home/username dir):
+INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/ $HOME/armnn-devenv/google/x86_64_pb_install/include/
+LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/ $HOME/armnn-devenv/google/x86_64_pb_install/lib/
+```
 * Setup environment:
-    ```bash
-    export PATH=$HOME/armnn-devenv/google/x86_64_pb_install/bin/:$PATH
-    export LD_LIBRARY_PATH=$HOME/armnn-devenv/google/x86_64_pb_install/lib/:$LD_LIBRARY_PATH
-    ```
+```bash
+export PATH=$HOME/armnn-devenv/google/x86_64_pb_install/bin/:$PATH
+export LD_LIBRARY_PATH=$HOME/armnn-devenv/google/x86_64_pb_install/lib/:$LD_LIBRARY_PATH
+```
 * Compilation with Make:
-    ```bash
-    make all
-    make test
-    make runtest
-    ```
-    These should all run without errors
+```bash
+make all
+make test
+make runtest
+# These should all run without errors
+```
+
 * caffe.pb.h and caffe.pb.cc will be needed when building ArmNN's Caffe Parser
 
-#### <a name="installBaarch">Build Boost library for arm64</a>
+## Build Boost library for arm64
 * Build Boost library for arm64
     Download Boost version 1.64 from http://www.boost.org/doc/libs/1_64_0/more/getting_started/unix-variants.html
     Using any version of Boost greater than 1.64 will fail to build ArmNN, due to different dependency issues.
-    ```bash
-    tar -zxvf boost_1_64_0.tar.gz
-    cd boost_1_64_0
-    echo "using gcc : arm : aarch64-linux-gnu-g++ ;" > user_config.jam
-    ./bootstrap.sh --prefix=$HOME/armnn-devenv/boost_arm64_install
-    ./b2 install toolset=gcc-arm link=static cxxflags=-fPIC --with-test --with-log --with-program_options -j32 --user-config=user_config.jam
-    ```
-
-#### <a name="buildCL">Build Compute Library</a>
+```bash
+tar -zxvf boost_1_64_0.tar.gz
+cd boost_1_64_0
+echo "using gcc : arm : aarch64-linux-gnu-g++ ;" > user_config.jam
+./bootstrap.sh --prefix=$HOME/armnn-devenv/boost_arm64_install

 * Clean the boost library directory before trying to build with a different architecture:
-    ```bash

 * Missing arm64 libraries for libz.so.1, these can be added by adding a second architecture to dpkg and explicitly installing them:
-    ```bash
-    sudo dpkg --add-architecture arm64
-    sudo apt-get install zlib1g:arm64
-    sudo apt-get update

+```
 * If apt-get update returns 404 errors for arm64 repos refer to section 5 below.
 * Alternatively the missing arm64 version of libz.so.1 can be downloaded and installed from a .deb package here:
       https://launchpad.net/ubuntu/wily/arm64/zlib1g/1:1.2.8.dfsg-2ubuntu4

+<br><br>
+
+### Unable to install arm64 packages after adding arm64 architecture
 * Using sudo apt-get update should add all of the required repos for arm64 but if it does not or you are getting 404 errors the following instructions can be used to add the repos manually:
 * From stackoverflow:
 https://askubuntu.com/questions/430705/how-to-use-apt-get-to-download-multi-arch-library/430718
 * Open /etc/apt/sources.list with your preferred text editor.
 
 * Mark all the current (default) repos as \[arch=<current_os_arch>], e.g.
-    ```bash
-    deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main restricted
-    ```
+```bash
+deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ xenial main restricted
+```
 * Then add the following:
-    ```bash
-    deb [arch=arm64] http://ports.ubuntu.com/ xenial main restricted
-    deb [arch=arm64] http://ports.ubuntu.com/ xenial-updates main restricted

 * Update and install again:
-    ```bash
-    sudo apt-get install zlib1g:arm64
-    sudo apt-get update
-    sudo ldconfig
-    ```
-##
-#### Undefined references to google::protobuf:: functions

 * Missing or out of date protobuf compilation libraries.
     Use the command 'protoc --version' to check which version of protobuf is available (version 3.12.0 is required).
     Follow the instructions above to install protobuf 3.12.0
     Note this will require you to recompile Caffe for x86_64
