-# CatchBoundary Example
+# ErrorBoundary Example
 
-If you want to handle _expected_ errors, you use a `CatchBoundary` to catch those types of errors. Think about HTTP-400-level errors like unauthorized etc.
+If you want to handle errors, export an `ErrorBoundary` from your route.
 
 ## Preview
 
 Open this example on [CodeSandbox](https://codesandbox.com):

 ## Example
 
-In this example, we have a list of users and one user that does not exist. When you navigate to the user that does not exist, our CatchBoundary renders in place of the component for that route.
