# Configuration Overview

*Article Topics:* [*Customization*](/getting-started/common-topics/customization.md)

The Configuration Admin in NATS allows for flexibility to you the client, giving you customizability around various systems in NATS.

The NATS configuration admin works in conjunction with the NATS configuration file, allowing clients a great deal of flexibility in customizing their NATS. The configuration file is stored in the NATS directory on your server as *includes/config.php*.

## Configuration Options

The following is a breakdown of categories and sub-categories in which you can find your configuration admin settings in.

* The [**Home**](/nats-admin/configuration/configuration-overview/home.md) options are the primary NATS settings. Some options can't be edited; please [submit a ticket](http://clients.toomuchmedia.com/) if you need these options changed.
* The [**Affiliates**](/nats-admin/configuration/configuration-overview/affiliates.md) options set affiliate defaults, requirements, postbacks, and other affiliate settings.
* The [**Billers**](/nats-admin/configuration/configuration-overview/billers.md) options set security options relating to billers and biller-specific configurations.
* The [**Cronjobs**](/nats-admin/configuration/configuration-overview/cronjobs.md) options change how NATS does scheduled tasks.

* The [**Security**](/nats-admin/configuration/configuration-overview/security.md) options configure who can access secure areas of your NATS program. Be careful editing these settings, as you can easily lock yourself out.
* The [**Surfer** ](/nats-admin/configuration/configuration-overview/surfer.md)options set tracking options, as well as signup form settings.
* The [**Third-Party**](/nats-admin/configuration/configuration-overview/third-party.md) options contain polling options related to your third-party providers.
