A good document that receives contribution from multiple users normally requires some ground rules and guidelines to ensure consistency. In edit mode, the Wiki will display the startup guide for editor on the home page. The startup guide is a great resource to explain to your editors the writing rules and guidelines for your Wiki. You'll want to use the opportunity here to explain formatting rules, layout, acceptable content and writing styles to produce a nice document.
Users can always return to this start page by clicking on Home from the action menu. You can edit the startup guide by going to the module's Settings page.
