 A Configuration Preset is a [configuration profile](./UsingTheNodejsWrapper.md#configuration-profiles) that has already been set up by the AWS Advanced NodeJS Wrapper team. Preset configuration profiles are optimized, profiled, verified and can be used right away. If the existing presets do not cover an exact use case, users can also create their own configuration profiles based on the built-in presets.

 ## Using Configuration Presets
 
 The Configuration Preset name should be specified with the [`profileName`](./UsingTheNodejsWrapper.md#connection-plugin-manager-parameters) parameter.

+
 An alternative way of loading plugins and providing configuration parameters is to use a configuration profile. You can create custom configuration profiles that specify which plugins the AWS Advanced NodeJS Wrapper should load. After creating the profile, set the [`profileName`](#connection-plugin-manager-parameters) parameter to the name of the created profile.
 This method of loading plugins will most often be used by those who require custom plugins that cannot be loaded with the [`plugins`](#connection-plugin-manager-parameters) parameter, or by those who are using preset configurations.
