The "how to" bit is redundant. We keep an anchor for backwards
compatibility.

All the howtos were under the "Commit hooks" docs, weird.

See: team#41180

Those basically worked, but I figured I would reword some of it. In
particular, @smith had the first step (that seemed obvious, but is
good to add explicitely anyway) of actually logging in first.

Then I also split out the "edit info" button which was all in one long
paragraph before (complete with a "lick" instead of "click" typo).

I also made it more explicit how to "add a new address" if we're in
that state, although I'm still not fully clear what happens in that
situation.

Other changes are stylistic and typos, mostly.

it's assumed that /swapfile exists in /etc/fstab, all installers should
be setting it up
