Each newly created course or group wiki requires a first page, which is the home page. When you access a new wiki for the first time, a message appears at the top of the page prompting you to create a home page. The home page always appears first in the wiki page list, making it an ideal page for instructions.
You or any course or group member can create the home page. No one can delete the home page, but if the wiki is open to editing, any course or group member may edit it.
The home page and all subsequent pages are created in the same way.
