  +### How do I keep my Backstage app up to date?
  +
  +In many ways one can view Backstage as a library rather than an application or
  +service. The `@backstage/create-app` tool that is used to create your own
  +Backstage app is similar to
  +[`create-react-app`](https://github.com/facebook/create-react-app) in that it
  +gives you a starting point. The code you get is meant to be evolved, and most of
  +the functionality you get out of the box is brought in via NPM dependencies.
  +Keeping your app up to date generally means keeping your dependencies up to
  +date. The Backstage CLI provides a command to help you with that. Simply run
  +`yarn backstage-cli versions:bump` at the root of your repo, and the latest
  +versions of all Backstage packages will be installed.
  +
  +While staying up to date with new releases and changes will keep your app up to
  +date, it can often be convenient to use the changes done to the
  +`@backstage/create-app` template as another method to stay up to date. For that
  +purpose, any changes done to the template are documented along with upgrade
  +instructions in the
  +[changelog](https://github.com/backstage/backstage/blob/master/packages/create-app/CHANGELOG.md)
  +of the `@backstage/create-app` package.
  +
  +### Why can't I dynamically install plugins without modifications the app?
  +
  +This decision is part of the core architecture and development flow of
  +Backstage. Plugins have a lot of freedom in what they provide and how they are
  +integrated into the app, and it would therefore add a lot of complexity to allow
  +plugins to be integrated via configuration the same way as they can be
  +integrated with code.
  +
  +By bundling all plugins and their dependencies into one app bundle it is also
  +possible to do significant optimizations to the app load time by allowing
  +plugins to share dependencies between each other when possible. This contributes
  +to Backstage being fast, which is an important part of the user and developer
  +experience.

  ### Do I have to write plugins in TypeScript?
  No, you can use JavaScript if you prefer. We want to keep the Backstage core
