How can I get Pi-Star Gui

Expand the SD card with the following command
sudo pistar-expand
​​exit from the command and let the pi reboot
Now set pi-star to read/write mode with this command:
​​rpi-rw
​​then enter this command to download the needed script:
​​wget http://pistar.uk/downloads/installGUI.sh
Change the permissions on the downloaded file:
chmod 755 installGUI.sh
Run the installer command:
./installGUI.sh
Be Patient!!! The installer takes a really long time. It has to download all the files needed to enable the GUI interface on Pi-star. Leave it alone, and let it do its job. It should restart when done, and boot to your new dashboard screen.
At this point, you need to use SSH, either direct, or through the dashboard. The next few steps will make it so you dont have to ‘login’ to the dashboard when using the on-board screen. It will still require login from any other device.
Edit the following file using your editor of choice (nano, vi, etc) ****Note – you must use ‘sudo’ with your editor to have proper permissions for editing the file.
/etc/nginx/sites-enabled/pi-star
Find the line that contains the following:
location ^~ /admin {
Create a new line after the line you found and add the following 2 lines:
satisfy any;
allow 127.0.0.1;
Save your file and exit.
