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