The link tag is short and simple: <a>. In between the opening and closing  <a> tags is what will become a link.

<html>
 <body>
  <a>Take me somewhere!</a>
 </body>
</html>
]]>

Easy! The web browser will display anything in between the opening and closing tag as a link.

If a tag contains a / sign, it's a closing tag and should be at the end.
