Provide an api docs

[SemyonL95]

Hi, have a question about web driver.

I don't really understand which parameters i have to pass in request for using bot builtin 'ExampleConversation', so could you please provide a documentation of api.

Agree, for now we haven't any documentation for web-driver api.
