Getting started guide

[menkari]

I've recently begun using the library and whilst its super helpful and the usage can be inferred from piecing together the official docs and the API, its quite cumbersome in areas like OrganizationSearchFilters without the Hello World examples. There's at least 1-3 rounds of trial and error implementation

I clear wiki outlining what endpoints have been implemented (done) but then how the specific endpoints have been implemented with filters and such and making sure that there's clear consistency as well as working examples.

Happy to contribute to this repo to get it done.
