 ## About

 `Toc` is a plugin for [**Grav**](http://getgrav.org) used to generate Table of Contents from a Markdown document based on special markers. The markers are `[TOC]` and `[MINITOC]`, where the latter can be used for a (minified) Table of Contents to give an overview of the current content of the section. By default, the Table of Contents links to the contents (`anchorlinks`) and adds visible permanent links (`permalinks`) to all headers. Further, all headers will automatically have unique id attributes generated based upon the text of the header. See how it looks like:
