+- A newer –not yet released, but fairly stable– version of Gepard can be downloaded from branch ```Tiling2Develop```.  
+- If you plan to use Gepard with a ThermoFischer FTIR microscope *and feel adventurous*, you can download from branch ```Gepard_GU```.
+
+In any of these cases, you will need Python 3.8, so please follow [Method 1](###-method-1-(recommended)) as a starting point to set up the environment. 
+
+In the newer versions, the file structure of the project has changed and Gepard is split into two separate modules handling the measurement and evaluation part. 
+The parent folder is named by default ```gepard-[name of branch]```, but you can call it anything you wish. 
+In subfolder ```gepard\cythonModules``` you will find the modules that need to be compiled: ```setup_getMaxRect.py``` and ```setuptsp.py```.  
+The two gepard modules are called from inside the parent folder with:
+```
+python -m gepard
+``` 
+and 
+```
+python -m gepardevaluation
+```
