+
+Open the Anacoda prompt, navigate to the folder you stored the ```yml``` file and type the following command, replacing ```xxx.yml``` with the name of the file you just downloaded:
+```
+conda env create -f xxx.yml
+```
+You have now created a new environment that contains everything you need to run GEPARD.
+To activate the new environment (assuming you are working in Windows) type:
+```
+conda activate GepardEnv-windows
+```
+
+The compilation of tsp modules and running GEPARD will need to be performed in this environment. 
+
+We strongly advise against modifying this environment for any purpose as this could interfere with the function of GEPARD.
