This document briefly summarizes what is required to add collapsible sections to a GitHub Flavoured Markdown file. The collapsible sections function when viewed on GitHub Pages, but they will not work when viewed on GitHub itself.
For a working example, see this document as viewed on GitHub Pages: * [https://oclipa.github.io/collapsible-sections-for-gfm/](https://oclipa.github.io/collapsible-sections-for-gfm/) The raw markdown can be viewed here: * [https://raw.githubusercontent.com/oclipa/collapsible-sections-for-gfm/master/README.md](https://raw.githubusercontent.com/oclipa/collapsible-sections-for-gfm/master/README.md)       ------ **Move along; nothing to see here...**
