 ### Module
 
+If you need to add authentication, validation, rewrite or add routes, you can use the project as a module in combination with other Express middlewares.
+
 ```javascript
 var jsonServer = require('json-server')
 
-// Express server
-var server = jsonServer.create()
-
-// Default middlewares (logger, public, cors)
-server.use(jsonServer.defaults)
-
-// Add other Express middlewares if needed (authentication, redirections, ...)
-// ...
+var server = jsonServer.create() // Returns an Express server
+var router = jsonServer.router('db.json') // Returns an Express router
 
- // Express router
-server.use(jsonServer.router('db.json'))
+server.use(jsonServer.defaults) // logger, static and cors middlewares
+server.use(router) // Mount router on '/'
 
 server.listen(3000)
 ```
 
 For an in-memory database, you can pass an object to `jsonServer.route()`.
-Please note also that you can use the `jsonServer.router()` in existing Express servers.
