The package includes a built-in configuration interface called the FOP2 Manager, which is accessible at:

https://your.server/fop2/admin

After completing a fresh installation, it is essential to access this manager before opening the main FOP2 panel for the first time. The system is not preconfigured, so initial setup must be done through this interface.

Important: Always log into the FOP2 Manager immediately after installation, complete the initial configuration, and only then proceed to access the main panel.
