There are a few options that you can customize within your .env file.
Panel URL
The most important thing that you should customize is your ikpanel URL. By default, ikpanel is deployed on root URL but you can change it by adding IKPANEL_URL variable in your .env file.
.env
IKPANEL_URL=/admin
With this option, you can reach ikpanel on "www.yourdomain.com/admin".
