# Brain Configuration

Thye brain configuration controls how the brain interprets, processes the questions you ask and presents the answers back.

It is made up a large number of configurable options, all of which have default values, so you don't need to set any when you first start using the bot.

The configuration sections are as follows

 * [Overrides](./Config_Brain_Overrides)
 * [Defaults](./Config_Brain_Defaults)
 * [Binaries](./Config_Brain_Binaries)
 * Braintree
 * [Services](./Config_Brain_Services)
 * [Security](./Config_Brain_Security)
 * Dynamic Maps and Sets
 * Tokenizers
 * Debug Files
