# Configuration

Note:Before starting the configuration, a new module instance must be created. [Click here for more information about creating Module instances](/v121/docs/platform-create-new-module-instance).  
  
Each module has an API and Logger section that need to be configured separately. The default settings will be sufficient for this, but users will need to actively open the API and Logger configuration settings and save the default values to fully apply the settings. [Click here for more information about API and Logger Configuration](/v121/docs/platform-api-and-logger-configuration).

Note:Please note that starting from **N3uron** version **1.21.5**, the API section has been completely removed from the configuration options.
