Checked quite well and made a lot of minor changes while keeping the information correct.  Changes were made to Installation.ex as well as Shortcuts.tex and checked into GIT.  The table looks great in the PDF version but has 2 blank columns everywhere in the HTML version.    I have not examined it to decide why and was hoping Andrea would know right away what the problem is (no hurry though).  If stuck, let me know and I will try to understand and fix it myself.
