User Documentation

Hi,

Is there any decent user documentation for Telligent v10 around. I've only come across documentation with very limited information or lots of broken links!!

For instance I know how set the layout\theme\config\widgets for the landing page of a particular group once it's been created. But how do you set\edit the "Default" layout\theme\config\widgets for the "Group" landing pages.

Thank you for your help in advance.
