I Need Table of Content (TOC) For My Wordpress Site

Hello,
Am currently using plugin to create Table of Content on my site, but it (TOC plugin) do add a lot of unused CSS and JS on wordpress pages.

So I need a simple script created that will create Table of Content on all pages / posts.

This plugin has No javascript or css added. Should be light enough.
