You will likely require a login for the Wiki (“Create account” link at top right), however at present the Help pages appear to be restricted. Note this text on the page linked in the question:
Later, you will be able to participate, and improve the help pages.
hey, here we are in 2016 and we still can’t improve the outdated documentation. For instance Compare Document - LibreOffice Help, it’s now “Track Changes” → “Compare Document”. Don’t make a wiki if the public can’t contribute, make something you fully support and maintain…
It’s already 2017
