+### Workshop Materials
+
+Workshop materials such as lesson plans and worksheets are written as simple [Markdown](https://en.wikipedia.org/wiki/Markdown) files. Each presentation slide deck is created as a Markdown-based [GitBook](https://www.gitbook.com). All generated assets are published to [GitHub Releases for download](https://github.com/tomeshnet/p2p-internet-workshop/releases).
+
+If you want to generate these assets yourself, simply run `./build` and you will find the generated assets in the `output` folder. The `./release` script is used to zip up the generated assets into archives convenient for publishing, which is the form you will find in the GitHub Releases.
+
+When using the GitBook presentations at a workshop, it is most convenient to clone this repository, navigate to the appropriate presentation directory of the module, and serve the gitbook locally by running `gitbook serve`, then navigate to [localhost:4000](http://localhost:4000) from your browser to see the slides.
