 To get started all you need to do from your project is #include "EcsPython.h", and link to the EcsPython library. Included with ECS:Python is a demo project (/example) written to assist developers in understanding how to use the API.
 
 ECS:Python requires a Python distribution to be installed on your system. Python can be downloaded from: www.python.org/download

+## Build
+
+```
+git clone https://github.com/cross-platform/ecs-python.git
+cd ecs-python
+mkdir build
+cd build
+cmake ..
+make
+```
+
+- *`cmake ..` will auto-detect your IDE / compiler. To manually select one, use `cmake -G`.*
+- *When building for an IDE, instead of `make`, simply open the cmake generated project file.*
+
+
+## Debugging on Windows:
+
+The Windows Python distros do not come packaged with a debug library: "pythonXX_d.lib".
+So, in order to get ECS:Python to compile in Debug mode:
+ 
+ 1. Open: "<python_install_dir>\include\pyconfig.h"
+ 2. Comment out the line "#	define Py_DEBUG"
+ 3. Search and replace "_d.lib" with ".lib"
