After you have navigated to the 'Connections' tab, click on 'Providers' to access a list of your current databases and other data providers. Here, you can add, edit, or delete providers. To add a database provider, click 'Add Provider' to open up the provider creation interface.

From here, you can create either a new database connection, upload a file to act as a data source, or select identity to set up a connection to a directory. Once you have selected 'database' from the provider option, the rest of the menu will appear allowing you to choose a connection type before setting up the connection details. Once you have filled all entries select 'save' to create your new database connection. Once you do, Illuminate will create a temporary authorization key used with this command to finish the set up:

curl -X POST 'http://{dataport_container_ip:port}/idp/addDBproperties' -H 'Authorization:Token from Illuminate connections page in Step 2' -H 'Content-Type: application/json' -d '{"DBHost": "","port": "1234","SID": "","ServiceName": "servicename","DBUsername": "username","DBPassword": "***********"}'
