Help:Substituting templates

Template substitution is an alternate way to embed information contained in a template. Substitution is performed by placing the code  between the template braces, before the template name, like this:



How does substituting work?
Normally, when the code for a template named  is added to a page, it will display that template based on how it was designed at Template:Something. However, when you edit the page, you will still see  in the wikitext, instead of the full code of the template.



However, if you substitute a template, the text  will actually be replaced with whatever coding for the template is at Template:Something. If you edit the page again after saving, you will no longer see  in the text.



Why would I use this?
One reason is for things like welcome templates. Substituting these can be a good idea because welcome templates may change over time, and it can be odd to have someone's talk page change long after they have seen the notice. In addition, substituting it can give a better impression, as actual code can look more 'human' than text saying.
