This plugin puts a table of contents on your page. You just need to type <code>[toc levels=3 title="Table of contents"]</code> in the page/post editor. That’s it! 
You dont need to edit your themes source code. The plugin allows you to set a title of the toc box. You can also choose which heading tags (h1,h2,h3,h4 etc) 
you want to have in the table of contents. For more information see installation page or the
