-# Running the Fed-BioMed GUI on JupyterHub
-
-Prerequisites:
-- node configuration must be created
-- your JupyterHub IP address
-- a network port from the table below
-
-## Network ports
-
-| user | port |
-| ---  | ---  |
-| francesco | 8484 |
-
-## Running the GUI
-
-The GUI's execution will be associated with a specific node. For this example, we will refer to it as `node-name`. 
-Open a new terminal and navigate to the `fedbiomed` directory, then run the following command
-```bash
-cd $HOME/fedbiomed
-./scripts/fedbiomed_run gui data-folder /datasets config node-name --port <your port from the table above> --host 0.0.0.0 start
-```
-
-## Accessing the GUI
-Copy the IP address that you used to access JupyterHub, and append `:<your port number>` at the end and paste it in your browser. 
-For example, if your address was `1.2.3.4` and your port is `8456`, you would insert `http://1.2.3.4:8456` in your browser search bar.
