 *   In the ETA GUI you can then specify the IP address and port number of the computer running the backend, which can just be ``localhost:5678`` if you run backend and frontend on the same PC. 
 
-*    ETA Backend uses enviroment variable ETA_HOST for IP address and port that you want to use for remote connection to this computer. It will try to detect the port automatically.
