 # GEPARD
 
 GEPARD - Gepard-Enabled PARticle Detection for Raman microscopes.
+
+Copyright (C) 2018  Lars Bittrich and Josef Brandt, Leibniz-Institut für 
+Polymerforschung Dresden e. V. <bittrich-lars@ipfdd.de> 
+
+Requirements:
+
+* python 3.6, PyQt5, OpenCV 3.4.1, numpy 1.14, scikit-image 0.13.1, scipy 1.1.0,
+  win32com, pythoncom, cython 0.28
+  
+* we advise the use of Anaconda (python 3.6): https://www.anaconda.com/download
+  this package contains most of the python libraries
+  however, opencv and scikit-image are missing
+  start anaconda prompt and install opencv:
+  pip install opencv-python
+  conda install scikit-image
+
+* we recommend working with a 64bit OS and also a python interpreter compiled 
+  for 64bit as many use cases require a lot of memory (16 GB better 32 GB 
+  recommended)
+  
+* the tsp module in externalmodules can be built with
+  python setuptsp.py
+  please note: for this step a valid compiler needs to be installed in the 
+  system; Otherwise use the precompiled tsp-module
+  
+If you plan on using the WITec Raman interface to control your device, please
+note: You use this interface at your OWN RISK! Make sure, that no obstacles
+block the objective and that you UNDERSTAND and VALIDATE the code, that controls
+the microscope! Start with "witectesting.py", which should read and move within
+small margins.
+  
+At the moment the program is an executable python script. Copy the folder with 
+all its content to some place and run (e.g. using anaconda prompt):
+python gepard.py
+
+It is possible to create a windows link file, that executes python with the
+gepard script as an argument and the working directory pointing to the folder
+containing gepard for convenience.
