 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')
 
-var server = jsonServer.create() // Returns an Express server
-var router = jsonServer.router('db.json') // Returns an Express router
+// Returns an Express server
