 ## What is swagger
 
-Whether you're building huge information systems or providing a single (but powerfull) REST web service, describing your API will give a better knowledge and therefore usage of your service. And If you can benefit from a well-known standard and its tooling suite... It's icing on the cake.

 ## The swagger-jack library: why and how
 
-We heavily use NodeJS in our project, and Express is the community most popular web framework. 
-It's principle is quite simple: you declare your routes (an urls and an http method) and associate each of them to a function with specific arguments.
-Second concepts: middleware. 
-A middleware is a function that behave like Java's filters: it's invoked for each incoming request and can process to it, enrich it and let other process it, or just ignore it.
