Are you asking how to edit a wiki in general or how I plan to do editing in class?
If you are new to Wiki then there is a good video in MoodleDocs. The easiest way to get started if to go directly to https://docs.moodle.org/35/en/Wiki_activity. Play the video a few times then we can help you understand it.
If you are asking me what I plan to do, well, that has not been established yet. For this first round, I am going to open it up to all students and see what happens. I will get more into it in a few days or a week or so. I can let you know when I figure it out. ( :
