 New apps feature a built-in sidebar extension (`app/nav`) that will render all nav item extensions provided by plugins. This is a placeholder implementation and not intended as a long-term solution. In the future we will aim to provide a more flexible sidebar extension that allows for more customization out of the box.
 
-Because the built-in sidebar is quite limited you may want to override the sidebar with your own custom implementation. To do so, use `createExtension` directly and refer to the [original sidebar implementation](https://github.com/backstage/backstage/blob/master/packages/frontend-app-api/src/extensions/AppNav.tsx). The following is an example of how to take your existing sidebar from the `Root` component that you typically find in `packages/app/src/components/Root.tsx`, and use it in an [extension override](../architecture/25-extension-overrides.md):

 ## Getting started
 
 Your plugin has been added to the example app in this repository, meaning you'll be able to access it by running `yarn start` in the root directory, and then navigating to [/app](http://localhost:3000/app).

-You can also serve the plugin in isolation by running `yarn start` in the plugin directory.
-This method of serving the plugin provides quicker iteration speed and a faster startup and hot reloads.
-It is only meant for local development, and the setup for it can be found inside the [/dev](./dev) directory.
