That would be a good starting point for the more sophisticated users however
most small networks have very uneven
clue distribution so I believe something in a FAQ format would be more
approachable to the small ISP/Network operator
and therefore more likely to be implemented even if they did not fully
understand the configuration. We also need to create documents which
explain what each of the configs do
