 ## In a nutshell
 
-- Really fast (yeah, like really fast. Up to 50% faster than Express)
-- API similiar to Express.
-- Compatible with existing Express middlware.
-- Extensible & plugable.
-- Less than 150 lines of code, with routing and all.

+
+If you have implemented a custom error function (see `onError` under [options](#rayooptions--)) you may invoke it at any time by calling the `step()` function with an argument.
+```js
+const rayo = require('rayo');
+
+const options = {
+  port: 5050,
+  onError: (error, req, res) => {
+    res.end(`Here's your error: ${error}`);
+  }
+};
+
+rayo(options)
+  .get('/', (req, res, step) => step('Thunderstruck!'))
+  .start();
+```
+In the above example, the error will be returned on the `/` path, since `step()` is being called with an argument. Run the example, open your browser and go to [http://localhost:5050](http://localhost:5050) and you will see "Here's your error: Thunderstruck!".
+
+If you don't have a custom error function, you may still call `step()` (with an argument), in which case the error will be returned using Rayo's standard function.
