text: Excerpts are often useful in sections that link to a more specific article using {{Main}}. Such sections are usually summaries of the main article, so their original content (if any) can be merged into the main article and the section replaced for an excerpt of the lead section (for an efficient step-by-step procedure, see Template:Excerpt#Replacing Template:Main).
