Hi Team, I want to write custom dbt. Can you please help me, where to start write custom dbt in meltano? Any docs there?

We haven’t been focusing on dbt integration at the moment (but we will make it better very soon!) That said, https://meltano.com/tutorials/create-custom-transforms-and-models.html#adding-custom-transforms is a still mostly valid tutorial. You should be able to make any models w/in the transform directory and run them.
