 The Python (>=v3.5) interface consists of a C/C++ shared library (.so on Linux or .dll on Windows) called gatdaem1d which contains time-domain forward modelling and derivative functions which are called by the Python interpreter.
 
 ## Compiling and installing the C/C++ shared libraries
-We are using Meson to automatically build the required C++ library.
 Ensure that the GNU C++ compiler is available, and FFTW has been installed.
 
+Mac OSX currently has issues using cmake and brew installed gcc compilers. So we are stuck using a Makefile. Simply type "make" in the python folder.  On Linux, the easiest option is to use "make" also.
+
+Two environment variables need to be set before compilation using "export cxx=g++" and "export FFTW_ROOT=<path to FFTW>".
+
+On Windows, follow the documentation in the root folder.  Once the library is compiled, go ahead and pip install.
+
 ## PIP install of the Python package
 - To install as a python package you can then,
 ```bash
-	cd [ga-aem-install-dir]/python
 	pip install .
 ```
-- Note that **`python`** may need to be **`python3`** on your system.
+- Note that **`python`** may need to be **`python3`** on your system, and make sure the correct environment is activated/sourced.
 
 ## Examples
 - The directory [ga-aem-install-dir]/python/examples contains an example of how to use the gatdaem1d package.
