Hidden documentation

I was reading the Unreal’s documentation for sometime. Then I went on vacation for about 3 weeks.
After my vacation, I try to return to the documentation site but somehow I loss the site. I spent couple of days
looking for this document and finally found this site with a small arrow look like this " > " on the top left corner of the
Unreal Engine 4 documentation. Don’t you think your webmaster could make this more noticeable?
