-The SDK is in early stage development and APIs and interfaces are still subject to breaking changes. We’d love your feedback as we build additional functionality!
+## Usage
+
+### Starting a new project
+
+Install the [Nitric CLI](https://nitric.io/docs/getting-started/installation), then generate your project:
+
+TypeScript:
+
+```bash
+nitric new hello-world ts-starter
+```
+
+JavaScript:
+
+```bash
+nitric new hello-world js-starter
+```
+
+### Adding to an existing project
+
+First of all, you need to install the library:
+
+```bash
+npm install @nitric/sdk
+```
+
+Then you're able to import the library and create cloud resources:
+
+```typescript
+import { api, bucket } from '@nitric/sdk';
+
+const publicApi = api('public');
+const uploads = bucket('uploads').allow('write');
+
+publicApi.get('/upload', async (ctx) => {
+  const photo = uploads.file('images/photo.png');
+
+  const url = await photo.getUploadUrl({
+    expiry: 300,
+  });
+
+  return ctx.res.json({ url });
+});
+```
