Internet-in-a-Box (IIAB) 6.4 Release Notes are here:

To install IIAB 6.4 onto (either) Raspbian Stretch on RPi3:

   curl | sudo bash

This includes ~12 server apps and typically completes within 2 hours.
A far faster 1-line installer is below, if you want just ~6 server apps:

   curl | sudo bash

Conversely a much larger (but far slower) installation is possible,
if you want to experiment with a full suite of ~20 server apps:

   curl | sudo bash

In all cases, an Ethernet (live Internet) cable installed into the back of
your Raspberry Pi 3 is REQUIRED during installation!  Need live community
support?  Choose a filename containing "-vpn" at
so OpenVPN and TeamViewer work out of the box :)

Prefer to install from scratch?  Full instructions:

Please post your specific needs to our discussion forums
where we aim to respond to all (conscientious) questions within ~24 hours.

      Thanks For Building Your Own Library To Serve One & All !

An *enormous* thank you to the many countries, communities and volunteers
dedicating themselves non-stop doing exactly that--hence our new IIAB 6.4.
