• Preparation
  Make sure you have a good & reliable SD card and a proper power supply. Archives can be uncompressed with 7-Zip on Windows, Keka on OS X and 7z on Linux (apt-get install p7zip-full). RAW images can be written with Etcher (all OS).

• Boot
  Insert the SD card into the slot, connect a cable to your network if possible or a display and power your board. (First) boot (with DHCP) takes up to 35 seconds with a class 10 SD Card.

• Login
  Log in as: root Password: 1234. Then you are prompted to change this password (US-Keyboard setting). When done, you are asked to create a normal user-account for your everyday tasks.

• Change the password.

• Create a new user called joinin and set the password.
  Keep pressing [ENTER] to use the default user information.

Set up JoininBox

• Continue work as the root user.
• Continue with the manual building steps
  or
• download and run the build script:

$ wget https://raw.githubusercontent.com/openoms/joininbox/master/build_joininbox.sh && sudo bash build_joininbox.sh --with-tor
