Hello Victor,
Thank you for your PR.
Just one thing. The way you create model/controller with FAQ. It is working.
Another approach is to have just One controller for the FAQ. And two tables. If we have three faq category, you will create another table for that. But if you have two tables like this:
faq { id, title, created_by } and faq_qa { id, faq_id, question, answer }
It will be very easy to have many faq category with many questions/answers instead of having one table for one faq category.
Also in the Faq controller you can implement all methods that you need instead of having many controller for each faq category.
