What should I do to make Vanilla Forums look like this?

I want a clean and simple no-brainer forum that looks like this:

http://www.macfix.de/

https://macnemo.de/forum/

Thanks in advance.

Look at the available themes , find one that resembles what you want and then edit it to perfect it.

That looks like the default theme, with the menu in the sidebar and a different base color.
