With reference to my recent post about the 'sapui5bin' repo on Github, I had also put together a Getting Started guide for SAPUI5 for some colleagues, with particular focus on getting up and running with a portable and independent environment you can have on your laptop. In the spirit of "you can never have too many getting started guides" (as I learn different things from different guides) I thought I'd make my guide available for your reading pleasure.
Here it is: Getting Started with SAPUI5
Taken from the Table of Contents, here's what it covers:
Introduction
Download and unpack SAPUI5
Choose a home development location
Set up Apache
Configure Apache
Access your local SAPUI5 docs
Set up git for Windows
Clone sapui5bin
Relax
Share & enjoy!
