Iinsert app in Digi esp for Python

Hi, I’m working on my python app for gattaring wireless sensor data, i want to insert my app in Digi esp for Python and to use YML file for chosing up the sensors that will be part of the network. Can someone help me with some tips how to do that?
For now i choose the iDigi Dia project (empty), and then… what i have to do?
