Revised installation procedure. Now the same for user and devs. No more hosting pre-built binary extensions, users build themselves.

 Installation
 ============
 
-You should use the following guidance to install gprMax if you are an end-user (i.e. you don't intend to develop or contribute to the software). Developers (or those intending to use gprMax in a HPC environment) should follow the Installation for developers section (http://docs.gprmax.com/en/latest/readme_install_devs.html#installation-for-developers).
+The following steps provide guidance on how to install gprMax:
 
-The steps are:
+1. Install Python and required Python packages, and get the gprMax source code from GitHub
+2. Install a C compiler which supports OpenMP
+3. Build and install gprMax
 
-1. Get the code
-2. Install Python and required Python packages
-3. (*Microsoft Windows only*) Install C libraries
-
-1. Get the code
----------------
-
-* Download the code from https://github.com/gprMax/gprMax
-
-    * Click on **Releases** from the top header and choose the release you want (latest is at the top).
-    * Download zip files of the **source code** and **binary extensions** for your platform (``windows-32bit`` for 32-bit or ``windows-64bit`` for 64-bit versions of Microsoft Windows, ``linux-64bit`` for 64-bit versions of Linux, or ``macosx-64bit`` for 64-bit versions of Mac OS X).
-    * Expand both zip files.
-    * Copy the contents (binary extensions) from the ``windows-32bit``, ``windows-64bit``, ``linux-64bit`` or ``macosx-64bit`` directory into the ``gprMax-v.X.Y.Z/gprMax`` directory.

-2. Install Python and required Python packages
+1. Install Python and required Python packages
 ----------------------------------------------
 
 We recommend using Miniconda to install Python and the required Python packages for gprMax in a self-contained Python environment. Miniconda is a mini version of Anaconda which is a completely free Python distribution (including for commercial use and redistribution). It includes more than 300 of the most popular Python packages for science, math, engineering, and data analysis.
 
-* Install the Python 3.5 version of Miniconda for your platform from http://conda.pydata.org/miniconda.html (You can get help with installing Miniconda from http://conda.pydata.org/docs/install/quick.html)
-* Open a Terminal (Linux/Mac OS X) or Command Prompt (Windows) and navigate into the top-level gprMax directory.
-* Update conda :code:`conda update conda`
-* Create an environment (using the supplied ``conda_env.yml`` environment file) for gprMax with all the necessary Python packages :code:`conda env create -f conda_env.yml`
-* Activate the new environment :code:`source activate gprMax` (Linux/Mac OS X) or :code:`activate gprMax` (Windows).
+* Install the Python 3.5 version of Miniconda for your platform from http://conda.pydata.org/miniconda.html (help is at http://conda.pydata.org/docs/install/quick.html)
+* Open a Terminal (Linux/Mac OS X) or Command Prompt (Windows) and run the following commands:
+    * :code:`conda update conda` (to make sure conda is up-to-date)
+    * :code:`conda install git`
+    * :code:`git clone https://github.com/gprMax/gprMax.git` (to get the latest gprMax source code from GitHub)
+    * Go to the top-level gprMax directory and execute :code:`conda env create -f conda_env.yml` (this will create an environment for gprMax with all the necessary Python packages)
+    * Activate the new environment :code:`source activate gprMax` (Linux/Mac OS X) or :code:`activate gprMax` (Windows).
 
 .. note::
     * When you are finished using gprMax the Miniconda environment can be deactivated using :code:`source deactivate` (Linux/Mac OS X)  or :code:`deactivate` (Windows).
     * If you want to install Python and the required Python packages manually, i.e. without using Anaconda/Miniconda, look in the ``conda_env.yml`` file for a list of the requirements.
 
-3. (*Microsoft Windows only*) Install C libraries
--------------------------------------------------
+2. Install a C compiler which supports OpenMP
+---------------------------------------------
 
-* Install the Microsoft Visual Studio 2015 C++ Redistributable (``vc_redist.x86.exe`` for 32-bit or ``vc_redist.x64.exe`` for 64-bit) from https://www.microsoft.com/en-us/download/details.aspx?id=48145.
+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 C++ Build Tools 2015 directly from http://go.microsoft.com/fwlink/?LinkId=691126 or by going to https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx and choosing Visual Studio Downloads -> Tools for Visual Studio 2015 -> Microsoft Visual C++ Build Tools 2015. Install using the default options.
+
+3. Build and install gprMax
+---------------------------
+
+Once you have installed the aforementioned tools follow these steps to build and install gprMax:
+
+* Open a Terminal (Linux/Mac OS X) or Command Prompt (Windows), navigate into the top-level gprMax directory, and run the following commands:
+    * If it is not already active, activate the gprMax conda environment :code:`source activate gprMax` (Linux/Mac OS X) or :code:`activate gprMax` (Windows)
+    * :code:`python setup.py build`
+    * :code:`python setup.py install`
+
+.. note::
+
+    * 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.
+    * If you want to remove/clean the built modules, e.g. before updating gprMax, you can use :code:`python setup.py cleanall`.
 
 **You are now ready to proceed to running gprMax.**
 
+
+Updating gprMax
+===============
+
+* Open a Terminal (Linux/Mac OS X) or Command Prompt (Windows), navigate into the top-level gprMax directory, and run the following commands:
+    * If it is not already active, activate the gprMax conda environment :code:`source activate gprMax` (Linux/Mac OS X) or :code:`activate gprMax` (Windows)
+    * :code:`git pull` (this will pull the most recent source code from GitHub)
+    * :code:`python setup.py cleanall`
+    * :code:`python setup.py build`
+    * :code:`python setup.py install`
+
