Examples of using fastai

I am trying to use fastai library for some tabular data problems I am currently doing and it is really time consuming because I cannot find code examples of how to use for various scenarios. The cryptic documentation also does not help much. The only examples I know of are the ones Jeremy goes through during the lessons. For similar problems it works fine but when the problem changes (for example, multi-class classification using tabular data) I get weird results.

Does anyone know of any good examples of using fastai for classification, regression, etc?
