Can you show me how to use by example?

I've tried to do what you describe in README but the output is not as I expected.

I implemented on non-framework project run on XAMPP with PHP 5.6.36

At first I tested with Postman and get 404 not found page, but after some configure, I got a different result but still just a 404 not found with Resource at [my-service-name] Not Found message.

I think I might come in the right way, but still not reached the goal.
