Site Builder Questions

Hi,

I'm going to build my first website, but I don't have any coding knowledge, so I tried out the Site Builder demo.

I tried to make a demo page, but it's almost impossible for me to make one because site builder is just so hard to use.

I want to ask:

1. How do I add more links and sublinks after that?
2. How do I insert information?
3. How do I change the site title/subtitle?

Thank you.
Jim
