The following comments in 1.1's config.yml will not show up if you are updating from 1.0:

#You can separately use the players display name with !PN! and their cause of death !CD!
#For example your prompt could look like 'This is the username of a minecraft character: !PN! and this was their cause of death !CD! , come up with an obscene and hilarious way to announce their death. If their cause of death includes "killed by" and a word you don't recognize, it is likely the username of another character.'

#Reminder that you need to tell the ai what it is that you are giving it.
