Templates are reusable portions of text and/or wiki markup that can be "included" in other pages by using the "double-braces" wiki syntax: {{Name of template}} The name of the template can have spaces (you don't have to replace them by _underscores_); the first letter is case insensitive (it can be capital or lower-case), but subsequent letters are case sensitive. The content of the template is stored in the same-named page in the Template: namespace, which would be linked to using the following "double-square-brackets" syntax: [[Template:Name of template]]
