# To install Internet-in-a-Box (IIAB) 7.2 / pre-release onto Raspberry Pi OS,
# Ubuntu 20.04 or Debian 10, run this 1-line installer:
#
# curl https://raw.githubusercontent.com/jvonau/iiab-factory/master/7.2-install.txt | sudo bash
#
# 1. WHEN YOU RUN 1-LINE INSTALLER FROM ABOVE
#    YOU THEN NEED TO TYPE IN YOUR PASSWORD IF ON UBUNTU/DEBIAN/ETC (for sudo)
#    ^^^ ^^^^ ^^^^ ^^ ^^^^ ^^ ^^^^ ^^^^^^^^
#
# 2. WARNING: NOOBS IS *NOT* SUPPORTED, as its partitioning is very different.
#    On a Raspberry Pi, WE RECOMMEND YOU INSTALL THE LATEST RASPBERRY PI OS:
#    https://www.raspberrypi.org/documentation/installation/installing-images/README.md
#    To attempt IIAB 7.2 on another Linux see the full/manual instructions:
#    https://github.com/iiab/iiab/wiki/IIAB-Installation#do-everything-from-scratch

# 3. An Ethernet cable is HIGHLY RECOMMENDED during installation, as this is
#    more reliable than Wi-Fi (and faster!)

# 4. Run 'sudo raspi-config' on RPi, to set LOCALISATION OPTIONS

# 5. OPTIONAL: if you have slow/pricey Internet, pre-position KA Lite's
#    mandatory 0.9 GB English Pack (en.zip) within /tmp -- you can grab a copy
#    from http://pantry.learningequality.org/downloads/ka-lite/0.17/content/contentpacks/en.zip

# 6. Follow on-screen instructions (TYPE 'sudo iiab-upgrade' TO RESUME IF EVER NECESS!)

# 7. About 1-2 hours later, it will announce that INTERNET-IN-A-BOX (IIAB)
#    SOFTWARE INSTALL IS COMPLETE, prompting you to reboot...TO ADD CONTENT!
