Gluster users - Aug 2013 - Difficult to navigate in documentation page of gluster.org

For example:

1. Click Documentation:
http://www.gluster.org/community/documentation/index.php/Main_Page
2. Click Developers:
http://www.gluster.org/community/documentation/index.php/Developers
3. Click Architectural overview and Gluster internals:
http://www.gluster.org/community/documentation/index.php/Arch

Now, looking at this page. I am completely lost where I am in the
documentation hierarchy.

Can we improve the documentation hierarchy so people are more easier
to read the docs?
