 # Accessing JupyterLab
 To access JupyterLab from your Raspberry Pi running with a GUI, you can open the browser and enter [127.0.0.1:8888](http://127.0.0.1:8888). When asked for a password just leave the field empty and press `ENTER` to continue.
 
-If you are running your Pi without a graphical user interface you can access jupyterlab using the Raspberry Pis hostname or IP-address at port 8888. If the hostname has not been changed this would be [raspberrypi:8888](http://raspberrypi:8888)

 This section is only relevant for a headless configuration when using an older version of Raspberry Pi Imager than 1.6 or if you need to change settings after you have already flashed the image to an SD-card.
 ### SSH

 WiFi can also be configured using a similar method. Create a textfile named `wpa_supplicant.conf` in the same folder as the `ssh` file above.
