• Run ./install.sh
• This should build and install all dependencies
• ./install.py or python install.py
• Follow instructions for initializing Pi config
• Sign client-req.pem with master CA from server

• To initialize a card you need to:
• Login to pi
• cd /opt/nfc/doorcmds/
• Determine your user_id from database
• echo <user_id> > init (example if your user_id=3 "echo 3 > init")
• Once the reader LED goes purple, hold a new card to the reader until the LED turns off
• Check the Node under the Admin controls to see the new card's entry in the database
• Rename and associate the card with appropriate person and enable if appropriate
