This is a documentation subpage for Template:Code of Federal Regulations. It may contain usage information, categories and other content that is not part of the original template page.

This template cites the Code of Federal Regulations with automatic links. It wikilinks the title and/or part if it exists on Wikipedia, and makes an external link to the U.S. government's GPO Access site for the subpart and section.

This template links to external sites. External links should not normally be used in the body of an article; see Wikipedia:External links for discussion of acceptable and unacceptable uses. **Using spaces in the parameters (ie. title, part, section, etc) will break the external link generated by the template
