 To benefit from auto updates, you have to implement and configure Electron's [`autoUpdater`](http://electron.atom.io/docs/latest/api/auto-updater/) module ([example](https://github.com/develar/onshape-desktop-shell/blob/master/src/AppUpdater.ts)).
 You also need to deploy your releases to a server.
