In this chapter, you learned how to connect to your BBB. BeagleBoard.org has streamlined the out-of-box experience, so there is a minimal setup on the device itself. You learned that the definitive reference manual for the BBB is the System Reference Manual, which should be your first stop for hardware-related questions about BBB. You learned about Emacs and how to create an embedded development environment with Emacs. Lastly, we identified several resources to find additional information on cryptography, electronics, and Linux.

In the rest of this book, you will build projects around the most popular and trusted software security packages: Tor, GNU Privacy Guide, and Off-the-Record messaging, all of which are actively used and maintained. In the next chapter, we'll use Tor and the BBB to help strengthen a censorship-resistant network.
