 Application Providers: Managing Applications
 --------------------------------------------
 
+In order for a developer to access PEDASI's capabilities within their application, their application needs to be first registered within PEDASI in order to obtain an API key they can use to authenticate with PEDASI. The following sections will walk you through adding and managing your first application. We will use the IoTUK Nation Database API (see https://iotuk.org.uk/iotuk-nation-database-api/) as a basic example.
