A category is a topic that pages can be filed under, so a reader can move through the wiki by subject instead of by guessing page names. A page joins a category by listing it in its settings, and the category gets a page of its own that lists every member. If you look at the very bottom of this page, you’ll see the categories it belongs to shown as small chips — that’s the feature describing itself.
Crucially, nobody maintains those lists by hand. A category’s membership is computed from the pages that claim it, so adding a page to a category is a one-line change on the page, and the category page updates itself.
Combining edit
Because membership is computed, categories can be intersected. Ask for the pages that are in two categories at once and you get exactly the overlap — a quick way to narrow a large topic without building a separate list for every combination. A wiki about cooking might cross “desserts” with “gluten-free” and get just the pages that are both.
Nesting edit
Categories can also contain categories. A page can be a member of one category and itself be a category that other pages join, which lets broad topics hold narrower ones — “vehicles” over “cars” over “electric cars.” There’s no rigid tree to set up in advance; the hierarchy is just categories pointing at categories, and it grows as the wiki does.
Housekeeping kept separate edit
Not every grouping is a subject. Some are notes-to-self about the state of a page — “needs sources,” “draft,” “to be merged.” Wikigit treats these maintenance categories as a class apart and keeps them out of the way of real topic categories, so a reader browsing by subject never trips over the wiki’s internal to-do list. Those same maintenance groupings feed the special pages that surface what needs attention.
