 When you run `sapper export`, Sapper first builds a production version of your app, as though you had run `sapper build`, and copies the contents of your `assets` folder to the destination. It then starts the server, and navigates to the root of your app. From there, it follows any `<a>` elements it finds, and captures any data served by the app.
 
-Because of this, any pages you want to be included in the exported site must be reachable by `<a>` elements. Additionally, any non-page routes should be requested in `preload`, *not* in `oncreate` or elsewhere.
