First, this assumes you have xowiki installed.
Next, mount up a site where you would like a wiki.
Then go to that link and you will see your folder.
We will create a category called recipes.
And you can add root categories as needed, then back to the assign categories screen.
Here is how it looks when we pick recipes as a mapped category to our new xowiki.
Notice I made it mandatory to choose a category, and now we have a category assigned.
Now we can add a page and use it as an index if you would like. I clicked on “Add XOWiki Plain Page” so I don’t have the wysiwig widget.
We will call this en:index. It is under category beer-recipes.
Now lets fix the folder to automatically use the index page.
Now you can add a page and you will see that it shows up under your category.
Here it is indexed on the en:index page
