+For addon authors, if the addon supports Fastboot mode, `ember-fetch` should also be listed as a [peer dependency](https://docs.npmjs.com/files/package.json#peerdependencies).
 This is because Fastboot only invokes top-level addon's `updateFastBootManifest` ([detail](https://github.com/ember-fastboot/ember-cli-fastboot/issues/597)), thus `ember-fetch` has to be a top-level addon installed by the host app.
