Clean-Up Recommendations

1. Document should be consistent throughout with su/sudo. That is, choose example commands to use su -c ... or sudo ..., but not both.
2. Formatting should be consistent with example commands—i.e., some commands are in

   pre

   and others are in 'bold'. I would recommend going with the pre blocks for each command that needs to be issued. That way it is very clear what has to be done without having to thoroughly read the body-copy for any intermediary steps.
