-#### Creating a page
-
-Creating a page is a simple matter of creating the page as an application
-in your framework of choice and then adding a loader to the `pages` array.
-For example, you can create a React application as the default export
-of a file `goodbye.tsx`. See
-[`hello.tsx`](https://github.com/openmrs/openmrs-esm-template-app/blob/master/src/hello.tsx)
-for reference. You could then add this as a page to the application:
-
-```typescript
-    pages: [
-      {
-        load: getAsyncLifecycle(() => import('./hello'), options),
-        route: 'hello',
-      },
