adding static pages to ecommerce site

[Fred Wang]

I am trying to add static pages to ecommerce site, the pages will
contain text, images and pdf. I found the the doc there is outdated
http://www.voidcn.com/link?url=https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Content+Management+How+to

From content manager UI of  the latest 16.04 release, I can see pages
can be easily made up and link to somewhere, but I don't not how to do
it step by step, can someone point me to the latest document?

Thanks,
