Beginner in Home Assistant use

Hello all together, i´m using Eltako 14 Modules since 2013 for my home. Now i want to add Home Assistant for new features. As a beginner it is quite difficult to find the information which i need to use the system. It begins with the debugging and logging of the system to get more infomation abt. communication ot enocean USB300 gateway. i added

Example configuration.yaml entry

logger:
default: debug

to configuration and got no answer at all.
Could anybody tell me what is wrong

Thanks a lot and all the best
Thomas
