• (Linux) Editing ~/.config/Librum-Reader/Librum.conf and setting selfHosted=true and serverHost to your server's url (e.g. serverHost=https://127.0.0.1:5001)
• (Windows) Opening the registry editor (Press Win + R and search for regedit), navigating to HKEY_CURRENT_USER\Software\Librum-Reader\Librum and setting selfHosted=true and serverHost to your server's url

Make sure to run the application before following the steps above, to generate the required files.
