+##Summary
+
+Kita akan membuat sebuah layanan yang mengimplementasikan RESTfull Web API di aplikasi kita.
+
+Cara menjalankan perintah berikut di direktori project kamu
+
+```
+$ express . \
+$ npm install
+```
+Buatlah sebuah source data atau database: \
+\* Bisa menggunakan file JSON atau SQLITE/POSTGRES DLL.
+
+
+####Route API
+Kamu bisa menggunakan pola perintah seperti dibawah ini :
+```
+| Route          | HTTP   | Description                 |
+|----------------|--------|-----------------------------|
+| /api/users     | GET    | Get all the users           |
+| /api/users/:id | GET    | Get a single user           |
+| /api/users     | POST   | Create a user               |
+| /api/users/:id | DELETE | Delete a user               |
+| /api/users/:id | PUT    | Update a user with new info |
+```
