Footnotes

Use the new <ref> tag to add footnotes to your articles. This tag is easy and convenient because it allows you to cite your sources within your text and then have them automatically numbered and added to your References section at the end of the article. When you want to cite a source simply use the <ref> tag to cite the source right next to the phrase that needs backing up. Example: Haliburton park is the largest park in the world<ref>Bill Harton (2005). http://www.linkhere.com. Retrieved Mar. 3 2005</ref>. Then, at the end of your article, add the following template to include all of the citations in your article: {{subst:footnotes}}
