-3. (*Developers only*) Install a C compiler which supports OpenMP
--------------------------------------------------------------------
-
-Linux
-^^^^^
-
-* gcc (https://gcc.gnu.org) should be already installed, so no action is required.
-
-
-Mac OS X
-^^^^^^^^
-
-* gcc (https://gcc.gnu.org) is easily installed using the Homebrew package manager (http://brew.sh) :code:`brew install gcc --without-multilib`.
-
-.. note::
-
-    Installations of Xcode on Mac OS X come with the LLVM (clang) compiler, but it does not currently support OpenMP, so you must install gcc.
-
-
-Microsoft Windows
-^^^^^^^^^^^^^^^^^
-
-* Download and install Microsoft Visual Studio 2015 Community (https://www.visualstudio.com/downloads/download-visual-studio-vs), which is free. Do a custom install and make sure under programming languages Visual C++ is selected, no other options are required.
-* Create a new environment variable :code:`VS100COMNTOOLS` which matches the value of the existing :code:`VS140COMNTOOLS` environment variable. To set an environment variable from the Start Menu, right-click the Computer icon and select Properties. Click the Advanced System Settings link in the left column. In the System Properties window, click on the Advanced tab, then click the Environment Variables button near the bottom of that tab.
-
-
-4. (*Developers only*) Compile the Cython extensions
-------------------------------------------------------
-
-Once you have installed the aforementioned tools follow these steps to build the Cython extension modules for gprMax:
-
-a) Open a Terminal (Linux/Mac OS X) or Command Prompt (Windows) and navigate into the top-level gprMax directory.
-b) Compile the Cython extension modules using: :code:`python setup.py build_ext --inplace`. You should see a set of :code:`.c` source files and a set of :code:`.so` (Linux/Mac OS X) or :code:`.pyd` (Windows) compiled module files inside the gprMax directory.
-
-.. note::
-
-    If you want to remove/clean Cython generated files, e.g. before rebuilding the Cython extensions, you can use :code:`python setup.py cleanall`.
