 ### Features
 
-* Tells you what's out of date.
-* Provides a link to the package's documentation so you can decide if you want the update.
-* Kindly informs you if a dependency is not being used in your code.
-* Works on your globally installed packages too, via `-g`.
-* **Interactive Update** for less typing and fewer typos, via `-u`.
-* Supports public and private [@scoped/packages](https://docs.npmjs.com/getting-started/scoped-packages).
-* Supports ES6-style [`import from`](http://exploringjs.com/es6/ch_modules.html) syntax.
-* Upgrades your modules using your installed version of npm, including the new `npm@3`, so dependencies go where you expect them.
-* Works with any public npm registry, [private registries](https://www.npmjs.com/enterprise), and alternate registries like [Sinopia](https://github.com/rlidwka/sinopia).
-* Does not query registries for packages with `private: true` in their package.json.
-* Emoji in a command-line app, because command-line apps can be fun too.
-* Works with `npm@2` and `npm@3`, as well as newer alternative installers like `ied` and `pnpm`.
