 # ScienceMode4_python_wrapper
 Python wrapper for the ScienceMode 4 protocol
+
+## Introduction 
+
+sciencemode_cffi is a python wrapper for the sciencemode library.
+
+This python library was tested on Windows 64bit together with Anaconda Python.
+
+This library is using [cffi](https://cffi.readthedocs.io/).
+
+## Preparation
+Unzip the correct version of the smpt library and copy the lib  into the lib directory.
+On Windows, build artifacts from [ScienceMode4_c_library](https://github.com/ScienceMode/ScienceMode4_c_library) can be used.
+
+## How to build for Windows
+Mingw 5.3 from Qt needs to be installed in `C:\Qt\Tools\mingw530_32`. Visual studio compiler needs also be installed.
+
+
+## Building the wheel
+Create a wheel with
+```
+python setup.py bdist_wheel --universal
+```
+## Installing the wheel
+You may correct the filename, check that the python version is matching the version in the filename.
+E.g. for python 3.9, the following version is valid:
+```
+pip install dist/sciencemode4_cffi-1.0.0-cp39-cp39-win_amd64.whl
+```
