[install] Improve overview to make purpose of guide clear
As per bug, making the purpose of the guide clearer, ensuring readers understand it is a minimum architecture for PoC purposes, and directing them to the arch guide for more complicated archictures. Change-Id: Ibeea8a6e8fa279d75c656c8073d2a1197b177fe3 Closes-Bug: #1646249
