Many people have expressed interest in using the raspberry pi for running the Tor onion router. Setting this up is quite trivial. The demo only applies to the Debian based Raspberry pi distro initially. Other documentation will follow for redhat based distros.
1. Boot your system and enable ssh support
2. Add the torproject apt repository to your pi by following [ https://www.torproject.org/docs/debian#ubuntu these instructions ]. The only tweak is when it describes adding the repo to sources.list, I reccommend adding that entire line instead to a file you create as /etc/sources.list.d/torproject.list .
3. Enjoy, you're now helping to support digital freedom around the world!
4. Alternatively if you're motivated you can configure your pi to Act as a relay.
