I downloaded the browser app.
I created a .realtebo ‘domain’ (is this term right?)
and a ‘www’ service.
Now I must upload files.
What kind of files?
You can upload a website. It can be static, or can be a dynamic web app by using the browser’s DOM API
Have a read back over in the community forum
This forum is for developers (how to build apps, how the API works etc), so you might find the community forum is best the information you need about the application examples - and you can ask for help in the support category over there.
