KDE Help Center /kdenlive/index.html does not exist

I just tried Kdenlive and want to learn more. I did some basic steps and think Kdenlive is great, but my knowlege is not.
I'm using Ubuntu 9.04 Gnome and installed kdenlive 0.7.3-0ubuntu2. When I click on the menu Help -> Kdenlive Manual I get the error of missing index.html. I see K3B has a manual so the Help Center is OK.
Where and how can I get the files I need? Which directory to save them in?
I see there are on-line tutorials and I will be using them.
Thanks.
