+```javascript
+module.exports = ({context}) => {

+
+You can also use async functions in this manner, as long as you `await` it in
+the inline script.
+
+Note that because you can't `require` things like the GitHub context or
+Actions Toolkit libraries, you'll want to pass them as arguments to your
+external function.
+
+Additionally, you'll want to use the [checkout
+action](https://github.com/actions/checkout) to make sure your script file is
+available.
