Template:Userbox/doc

Description
Userboxes are small notices on users' profile pages that contain information about a user. Rather than creating a new template for every custom userbox, new userboxes should be subpages of the Userbox template, which can be created by navigating to.

Making a userbox
Userboxes are highly customizable. Users can implement infoboxes for personal use by inserting the template into their profile pages and filling out each field, or save widely-used customizations on subpages to allow for standardized premade userboxes.

In this example, a userbox named Egoist is created at Template:Userbox/Egoist, as a subpage of the Userbox template. Others who wish to use the userbox on their profiles can simply add  to their profile pages.
