Create a FAQ

I have seen during the past few months that I am often re-explaining why we did this choices and things like we did.

I think it is time to start a FAQ in the kinto documentation in order to fix this and to have a easy entry point for people to get answers about the kinto ecosystem.

An example could be: https://docs.djangoproject.com/en/1.8/faq/

Start by reviewing the Kinto documentation structure and the linked Django FAQ example to identify where a FAQ would fit. Gather the recurring explanations mentioned in the issue and document them as an accessible entry point for the Kinto ecosystem; done means the FAQ exists in the documentation and answers those common questions.
