 ## How to run this

+### cli

+### webui

 As the user intended to run the server:
 
-    pip install --user git+https://github.com/Programvareverkstedet/grzegorz_clients.git#master
-    grzegorz-webui --host 0.0.0.0 --port 80
+    pip install --user git+https://git.pvv.ntnu.no/Grzegorz/grzegorz-clients.git#master
+    grzegorz-webui --host-name 0.0.0.0 --port 80
 
 It's rather insecure and could use a reverse proxy and some whitelisting. ;)
