+Compiling ECS::Python on Windows:
+
+Firstly, you'll need to ensure that the correct version of Python is
+being referenced in the CMakeLists:
+
+ 1. Open CMakeLists.txt
+ 2. Update the paths under "if(${CMAKE_SYSTEM_NAME} MATCHES "Windows")"
+
+Secondly, the Python distro does not come packaged with the debug library:
+"pythonXX_d.lib". So, in order to get ECS:Python to compile in Debug mode:
+ 
+ 1. Open: "PythonXX\include\pyconfig.h"
+ 2. Comment out the line "#	define Py_DEBUG
+"
+ 3. Search and replace "_d.lib" with ".lib"
