-The first version of this syllabus is created by [Toronto Mesh](https://tomesh.net) contributors: [@benhylau](https://github.com/benhylau), [@darkdrgn2k](https://github.com/darkdrgn2k), [@dcwalk](https://github.com/dcwalk), [@uditvira](https://github.com/uditvira), [@Shrinks99](https://github.com/Shrinks99), and [@Pedro-on-a-bike](https://github.com/Pedro-on-a-bike). While most of the material is created new, the course also incorporates many prior works listed [here]({{ site.baseurl }}/articles/general/general-extra-resources.pdf), or otherwise reference in their individual course modules.

 Hands-on activities rely on software from many projects: [mesh-orange](https://github.com/tomeshnet/mesh-orange), [mesh-router-builder](https://github.com/benhylau/mesh-router-builder), [mesh-workshop](https://github.com/benhylau/mesh-workshop/), [steamlink](https://github.com/steamlink), [cjdns](https://github.com/cjdelisle/cjdns/), [Yggdrasil](https://yggdrasil-network.github.io/about.html), [IPFS](https://ipfs.io/), [Secure Scuttlebutt](https://github.com/ssbc/). Course material generation uses [markdown-pdf](https://github.com/alanshaw/markdown-pdf) and [gitbook-cli](https://github.com/GitbookIO/gitbook-cli). The course website is built with [Jekyll](https://jekyllrb.com/), and the theme is from [Mozilla's Open Leadership Training Series](https://github.com/mozilla/open-leadership-training-series). Icons from [Font Awesome](http://fontawesome.io/) and [Jake Ingman](https://thenounproject.com/search/?q=mesh&i=74809) are used.
