The following walk through assumes you're using linux and knowledge of terminal. The basic idea of getting a node (router) on the mesh consists of flashing (copying files to the flash) an operating system to node and installing additional drivers and packages. We use [https://openwrt.org/ OpenWRT] as the operating system on our embedded devices (routers), then connect to the node (via [https://en.wikipedia.org/wiki/Secure_Shell SSH]) and install mesh the related software and configure it. This operating system is meant to fit on small amount (4MB) of flash memory. | The following walk through assumes you're using linux and [https://help.ubuntu.com/community/UsingTheTerminal knowledge of terminal].
