To add a template to this category:
- If the template has a separate documentation page (usually called "Template:template name/doc"), add
- [[Category:European championships sport navigational boxes]]
- to the <includeonly> section at the bottom of that page. Otherwise, add
- <noinclude>[[Category:European championships sport navigational boxes]]</noinclude>
- to the end of the template code, making sure it starts on the same line as the code's last character.
