Table of Contents
The website of the Tomancak Lab
Reproduced verbatim from the authors' answer on Stackoverflow:
My colleague @schmiedc and I have created a GreaseMonkey script that installs a new TOC button left of the h1 button which uses the excellent markdown-js library to add/refresh a table of contents. The advantage over solutions like doctoc is that it integrates into GitHub's wiki editor and does not need users to work on their command-line (and require users to install tools like node.js). In Chrome, it works by drag 'n dropping into the Extensions page, in Firefox you will need to install the GreaseMonkey extension. It will work with plain markdown (i.e. it does not handle code blocks correctly, as that is a GitHub extension to markdown). Contributions welcome.
Test drive the script here https://github.com/kgashok/tomancaklab.github.io/wiki
