WikiIndex:How do categories work

WikiIndex:How do categories work — this 'meta' article here on  describes the requirement to add further categories to an existing article here on WikiIndex beyond its 'main topic'. This  page describes the additional command (or wiki syntax) which may be used within the description prose area, or as separate categories listed below the prose description at the very bottom of the edit box.

Examples

 * ArborWiki
 * ICANNWiki
 * DavisWiki
 * Game Design Wiki

Basic overview

 * Add relevant categories (and / or tags) to articles; try to be consistent and use CamelCase where there are multiple words such as 'ProgrammingLanguages'.
 * As new categories are added (without any text within said new category), category pages will naturally appear in the Special:WantedPages section; create these 'red link' category pages as needed. Also, if these category pages are subordinate to larger categories, categorize them appropriately.  i.e. the category 'Lisp' should be a sub-category of 'Programming', and hence when you (originally) create(d) the category 'Lisp', categorize that category pages in 'Programming'.
 * Top-level categories should be categorized to 'Wiki Topic', which is the highest level. From time to time, the WikiIndex article page (as indeed many other existing article pages) will require manual updating of the top- and high-level categories.
 * A list of every category used at WikiIndex — whether or not its actual category page has been 'created' (ie, a red link category), much less whether that category has been properly categorized — is at Special:Categories.
