As of 7.4, we have had the ability to specify a default input format which has complicated peoples initial experience installing forena. See #2380421: Test graphs show as grey rectangle.

I just committed some code changes that would allow from the Forena Configuration screen, the ability to skip running all reports through the Drupal text format/input filter system. The administration screen has been updated with a new option, and the default behavior from 7.x-4.1 forward will be that no input format is used. This will help to make a lot more things just "work" out of the box.

The question posed in this issue is how the documentation should be updated to describe this. I've made some initial edits in the dev branch, but am curious about others feedback on this, and the new user interface for the forena configuration screen.
