Change-Id: I7d79bce6a88d06a0573be3e02ae43f547523d4d8
Add description and keywords to the walkthrough.

Change-Id: I182333a2d5103a0df146da29e0de814bedc2fa63
Link to the commit messages docs from the walkthrough.

This is the firt introduction to commit messages, so it's useful to
also link to the more detailed docs that are available.

Replace a non-code block with a suitably labelled <pre>.

This avoids trying to syntax-highlight a log message as python.

Minor spelling fix in the walkthrough.

Fix where the walkthrough says user accounts come from.

While we may have intended to hand them out at KickStart, this has
never actually happened (to my knowledge) and we now delegate this
to team-leaders via a web interface (userman/nemesis).

Disable Google Analytics

We don't use it, so it's only extra page load time.
