I'm stuck on the first step of the "Getting Started" guide.<p>1. I've downloaded helloworld.zip to my local computer, I think.
2. I open the filer.app.js by clicking the link on the webpage. This open a 90s.dev instance right on the page.
3. Then i'm supposed to mount helloworld/app as app and click it, so i click the mount button, it asks for the drive name, hi put in helloworld/app and click mount but nothing happens.<p>I must be missing how you're supposed to get helloworld.zip into the 90s.dev instance... how do you upload it into the instance?
