 If you're unfamiliar with now runtimes, please read the [runtime docs](https://zeit.co/docs/runtimes) first. This runtime can be used like any other Community Runtime.
 
 ```json
+// now.json
 {
-	"functions": {
-		"api/**/*.ts": {
-			"runtime": "[email protected]"
-		}
-	}
+  "functions": {
+    "api/**/*.ts": {
+      "runtime": "[email protected]"
+    }
+  }
+}
+```
+
+```ts
+// api/hello.ts
+import { Context, Event } from 'https://deno.land/x/lambda/mod.ts';
+
+export async function handler(event: Event, context: Context) {
+  return {
+    statusCode: 200,
+    body: `Welcome to deno ${Deno.version.deno} 🦕`,
+    headers: {
+      'content-type': 'text/html; charset=utf-8',
+    },
+  };
 }
 ```
+
 That's the simplest way to use this runtime!
 
+## Advanced usage
+
+You can place a `build.sh` function in the root of your deploy directory. This will be executed before the lambda is built.
+
+## Credits
+
+This was only possible due to the great work of [Andy Hayden](https://github.com/hayd) who made the first attempts at running [deno in a lambda function](https://github.com/hayd/deno-lambda).
