You create a page called:

Template:{Template Name}

without the brackets. Then you enter a whole ton of wikitext that makes the template, and then you include the name of the template in double curly braces in a page to insert the content of the template page into another page. If you don't know wikitext, it's better to have someone who does make the template.
