I want to try for the first time to develop a tap for a source system with the meltano sdk for taps. I looked at the documentation some time ago and as far as I can remember there was a page with a more detailed "tutorial". There is a page linked in the SDK Dev documentation that unfortunately no longer works: https://meltano.com/tutorials/create-a-custom-extractor.html I could find this page: https://docs.meltano.com/tutorials/custom-extractor But this page describes the sdk unfortunately only very general Is there any resource for more information about the "development process" of a tap with the sdk?
