 Download Anaconda from https://www.anaconda.com/download. Choose the Python 3.7 version and follow the installer instructions. For help regarding installation, please refer to the Anaconda installation guide. Anaconda includes most of the required python libraries, however some packages need to be installed manually. To do that, start an Anaconda prompt from the Start Menu (Windows) or re-open a terminal (Linux, MacOS) and type the following:

+## Start Gepard
 
 In the Anaconda prompt (Windows) or terminal (Linux, MacOS) navigate to the location containing the folder `gepard`. You can now start using Gepard in Simulated Raman Mode by typing:
 ```
 python -m gepard
 ```
 
+## Connect to a Raman microscope
+
+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.
+
+You will need to create a Gepard configuration file. In a text editor write the following (edit the magnification to match your used objective):
+```
+[Interface]
+raman_interface = WITEC_CONTROL
+
+[General Microscope Setup]
+magnification = 20
+```
+Save it as `gepard.cfg` in the Gepard folder. 
+
+To return to Simulated Raman Mode, set:
+```
+raman_interface = SIMULATED_RAMAN_CONTROL
+```
