+# Express REST API with Middleware
+
+This project contains a basic REST API built on express.js featuring file-system persistance, cors, and testing. You can access the API by making an HTTP request to one of the endpoints listed below.
+
+## Resources
+The following resources are available for storage and retrieval:
+
+Note: ids are automatically generated.
+
+```js
+Book {
+  id: '6c5036a6-913d-4475-91b0-084e4115e61b'
+  title: 'Hamlet'
+  author: 'William Shakespeare'
+  date: 1599
+  genre: 'Drama'
+}
+```
+
+## Book Endpoints
+
+### GET `/api/book`
+Gets an array of Book ids.
+
+### GET `/api/book/:id`
+Gets a JSON representation of a Book with the specified id.
+
+### PUT `/api/book/:id`
+Updates a Book with the specified id. The body of the request should be a serialized JSON object containing the updated property values.
+
+### POST `/api/book`
+Creates a Book object. The body of the request should be a serialized JSON object containing the Book's property values.
+
+### DELETE `/api/book/:id`
+Deletes a Book object with the specified id.
