I like the layout and style of Conluence documentation, can I reproduce it?

[Fedor Fedorchenko]

I like very much how the Atlassian Codocumentation is organized and how it looks.

How can I reproduce it in my own knowledge base? 

[Nic Brough -Adaptavist-]

It's Confluence with Scroll Viewpoint added to it.   While there's some config to be done, you can pretty much take both of them off-the-shelf as a starting point, and get most of what you see on Atlassian's site.
