Good, I just installed Slim version 3.0 on my local server, I have only one folder vendor where is all your engine ...
Some small example of how to start using it, folders, files, it is not necessary to have a database, if not something to start with.
I try to put together a following api
localhost/disvoverspain/v1/route that is listed all and
localhost/disvoverspain/v1/route/1 that record 1 is listed
as you configure slim, folders files etc.
