Understanding the code
+
+
+The first thing we do is bring The [Wing Cloud Library](/docs/api/category/cloud) to our application. We do this using the `bring` keyword.
+
+```js
+bring cloud;
+```
+
+The Cloud Library provides a list of cloud resources. Each resource you use has a set of [preflight and inflight APIs](/docs/concepts/inflights).
+
+
+
+Next, we create the new API resource. We do this by defining a new api using the Cloud Library.
+
+```js
+// Create a new API using the Wing Cloud Library (preflight code)
+let api = new cloud.Api();
+```
+
+The API is defined and now we can add routes to it. The API is defined within the `preflight` context.
+
+:::info What is preflight?
+Preflight code runs once, at compile time, and defined your application's infrastructure configuration. This configuration is then consumed by an infrastructure provisioning engine such as Terraform, CloudFormation, Pulumi or Kubernetes.
+
+You can read more about [preflight here](/docs/concepts/inflights#preflight-code).
+:::
+
+
+
+Finally we add the `GET /notes` route to our API.
+
+```js
+// GET /notes returns dummy data
+api.get("/notes", inflight () => {
+ // inflight code
+ return cloud.ApiResponse {
+ status: 200,
+ body: Json.stringify([{id: 1, content: "Hello world"}])
+ };
+});
+```
+
+Using the `API` preflight api, we can attach a new `GET` path to our API. Here we add `/notes` to the API.
+
+We defined an `inflight` function that is called when the route gets triggered.
+
+:::info What is inflight?
+Inflight blocks are where you write asynchronous runtime code that can directly interact with resources through their inflight APIs. Inflight functions can be easily packaged and executed onto compute platforms like containers, CI/CD pipelines or FaaS.
+
+You can read more about [inflight here](/docs/concepts/inflights#inflight-code).
