 ### Module
 
-You can use JSON Server as a module:
-
 ```javascript
 var jsonServer = require('json-server')
 
-var server = jsonServer.create()         // Express server
-server.use(jsonServer.defaults)          // Default middlewares (logger, public, cors)
-server.use(jsonServer.router('db.json')) // Express router
+// Express server
+var server = jsonServer.create()
+
+// Default middlewares (logger, public, cors)
+server.use(jsonServer.defaults)
+
+// Add other Express middlewares if needed (authentication, redirections, ...)
+// ...
+
+ // Express router
+server.use(jsonServer.router('db.json'))
 
 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.
