API docs Getting started should point to guides

[kyyberi]

Describe the Pain

While reading the https://docs.oftrust.net/#getting-started I expect to find two paths based on am I integrating new data source or considering to use data products in applications.

Simply provide the paths as titles. Add small description and and then link to master guide to start with (for both paths separate). Those guides might reference API docs endoints in various APIs.

Indicate the importance in number

(1. Critical, 2. Important, 3. Nice-to-have)
