Improve the documentation

Hi, I have two comments that can improve the documentation:
1- Please indicate in the page on the top whether it is for SDK V1 or V2. If it is in the page, I didn't notice it. Somewhere on the top will be better.
2- For each method or class, please include link to the examples, so that it is easy to follow without further search. Examples are the Pandas Python library that has examples (https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.merge.html).
