I will see what I can find for you, but this should be good to help you get started:
Before launching any new web site or service, you should always test it personally or privately for a while so that you, as the admin, can get a handle on how everything works, and so that most problems that affect your implementation can be ironed out before you go live. This will ensure that everything goes smoothly later and that you can answer user inquiries with confidence later on. This isn't just limited to VaultWiki or wikis, but you should write a page or two explaining how your site should be used, and how to use it properly based on those rules.
So with VaultWiki, the first thing you want to set out to do is defining the structure of your wiki. If you want to draw a tree diagram on paper first, it may be helpful. Basically, you want to answer a few basic questions:
- How will your wiki be organized? Some people organize by type of content (images, regular pages, translations, etc), by theme (tragic, inspiring, historical), or by specifics (books by author X, GE refrigerators, dog breeds). To keep it simple, try to start with only 4 or 5 different containers. You can always add more later or reorganize, once you're more comfortable with the software.
- Do you want all areas to be fully editable by your users, or do you want to make some content only controlled by admins? There are ways to protect admin content from being edited, but some people like creating entirely separate areas for admins vs regular users -- for example, you may want to use some tools that you don't trust regular users with (like raw HTML).
Once you have an idea of how the wiki's basic organizational structure will look, you can go ahead and duplicate it in Structures > Area Manager in the VaultWiki Admin Panel.
Then you will want to setup your Usergroup Permissions. These are the global permissions for your users across your entire wiki, based on what usergroup they belong to. They will be the "default" settings for your user permissions.
If you want your users to have different rights in a specific wiki area, you can modify that by clicking the Keys next to the area's name in the area manager.
If you are making a multilingual wiki, make sure to create the languages you want to let users post in by visiting Languages > Language Manager in the VaultWiki Admin Panel.
After that, most best practices tend to relate to what you should put in a wiki page to make it considered "a good article". If you have any more questions, please don't hesitate to ask.
