There are two main ways to use templates on articles: transclusion also called "inclusion", and accomplished by using Template name, and subclusion also called "substitution". The former will include the content of Template Name on the fly whenever the article is loaded, while the latter will permanently insert the content of the template into the article.With substitution, even if the template content is modified at a later date, the article's content will not change.The common method for using template messages is transclusion, implemented by usage of a tag with the form template name, in whatever article or talk page one wants the template code/text to be shown
