When I've been using open source libraries without significant docs I've mostly benefitted from actually reading the code. Assuming you have the source. This can be incredibly varying in complexity. I've found a large Elixir codebase, as a functional paradigm easier to grasp compared to a single library in heavy OOP style in Python. Python not enforcing much structure and this particular library doing a lot of inheritance which complicates the state and modelling in my head a lot. So it varies a lot per code base and experience. But if you have the code, that's what I'd use.
