I always tend to get interested in some technology or library and go straight to the docs. They usually have intro or tutorial/gallery type sections that help you get started. It helps to have a use case in mind and imagine applying it as you read through the API details. This worked for me equally well for ML libraries as it did for learning kernel stuff (except for the latter i went to a reference book). It's real similar to just doing your normal software job, but in this case it's just for fun!
