Important Wiki Documents
There are a number of "important" wiki documents, i.e. documents with well-known names that are used in parts of the interface besides the normal knowledge base.
These documents make it possible to update content on, for example, the home pages without requiring code changes.
In all cases, the title of the English document matters, but the slug, or title of the localized versions, does not.
For a list of the documents, check out the Managing Landing Page Content article on SUMO.
