# Overview of configuring NaturalConference

Before you develop applications using NaturalConference, configure NaturalConference for your system. NaturalConference requires appropriate declarations in three configuration files:

Configuration file | Description
--- | ---
Natural Access configuration file (cta.cfg) | Defines all Natural Access services used by the application.
Board keyword file | Contains sections for declaring DSP functionality and associated DSP files to be loaded on AG and CG boards. The NaturalConference DSP file must be declared in this file. NaturalConference provides sample board keyword files.
NaturalConference configuration file (cnf.cfg) | Contains the conference resource declaration. NaturalConference uses this information to create and manage conference resources. If the NaturalConference configuration file does not exist, or if it does not contain a valid declaration consistent with the board configuration file content, NaturalConference cannot open any conference resources. NaturalConference provides sample NaturalConference configuration files.

The following illustration shows how NaturalConference uses the configuration files:
