-Installing both `git` and `make` by following instructions on the websites is

source codes.
-
-1. Install the 32-bit `libc` with one of the following system-specific
commands:
-
- ```bash
- sudo apt-get install libc6-dev-i386 # In Ubuntu
- sudo yum install glibc-devel.i686 # In RHEL (Red Hat Linux)
- sudo yum install glibc-devel.i386 # In CentOS 5.8
- sudo yum install glibc-devel.i686 # In CentOS 6/7
- ```
-
-2. Download and extract the `gcc` source code with the prerequisites:
+#### BLAS library
- ```bash
- wget http://mirrors.concertpass.com/gcc/releases/gcc-4.8.5/gcc-4.8.5.tar.gz
- tar -zxf gcc-4.8.5.tar.gz
- cd gcc-4.8.5
- ./contrib/download_prerequisites
- ```
+MXNet relies on the
+[BLAS](https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms) (Basic
+Linear Algebra Subprograms) library for numerical computations. You can install
+any one among [ATLAS](http://math-atlas.sourceforge.net/),
+[OpenBLAS](http://www.openblas.net/) and
+[MKL](https://software.intel.com/en-us/intel-mkl).
-3. Build `gcc` by using 10 threads and then install to `/usr/local`
- ```bash
- mkdir release && cd release
- ../configure --prefix=/usr/local --enable-languages=c,c++
- make -j10
- sudo make install
- ```
+#### Optional
-4. Add the lib path to your configure file such as `~/.bashrc`:
+* [OpenCV](http://opencv.org/) for Image Loading and Augmentation
+* [NVDIA CUDA and cuDNN](https://developer.nvidia.com/cuda-downloads) for
running MXNet with GPUs
- ```bash
- export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib64
- ```
-</div>
-</div> <!-- linux -->
+### macOS
-<div class="windows">
+Refer to the [MXNet macOS setup guide](osx_setup.html) for detailed
instructions.
-1. If [Microsoft Visual Studio 2015](https://www.visualstudio.com/downloads/)
is not already installed, download and install it. You can download and install
the free community edition.
-2. Download and Install [CMake](https://cmake.org/) if it is not already
installed.
-</div>
+### Windows
-<div class="macos">
+Refer to the [MXNet Windows setup guide](windows_setup.html) for detailed
instructions.
-Install [Xcode](https://developer.apple.com/xcode/).

+### Ubuntu
-#### BLAS library

for build from source instructions as well as installation of language bindings.

Review comment:
Are we sure that we need instructions how to build gcc? Is there any use
case where it can not be installed with a package manager?
Say: `sudo apt install gcc-4.8` or `sudo apt install gcc-4.9`
