Use
[edit]Place this template, with the name of the article to be merged into this article or section after a pipe (or vertical bar symbol):
{{merge from|name of article to be merged into this article or section}}
on its own line at the end of the article (or section of an article) that content needs to be moved to from the other, lesser article
Purpose
[edit]Sometimes we get new orphan articles or neglected stubs about the same place or topic. Although the new article or old stub is tagged for merger into this article, relatively few editors may stumble across it. Many more editors will visit the better linked article (or section) on which this template is placed, that might otherwise remain oblivious to the (duplicated/redundant) article that should be merged into it.
