Very nice introduction, but I have a couple of comments.

In "Specifying revisions" you say that '^' and '~' are equal, but that
is not true. ^ is used to select the first parent of a commit, ^2
selects the second parent of a merge commit (and ^3 selects the third
parent of an octopus merge), while the '~' is used to go back any
number of generations, following the first parents of each commit (~
selects the first parent, ~2 selects the first grand-parent etc).

Also, I think you might scare users away from 'git reset':

  git reset resets the branch to a specified state invisibly and
  without possibility to go back. Ever. Your call.

That's not true, since any "modern" git has reflogs enabled. If you do
'git reset --hard HEAD^^^' and then realize it was a mistake you can
just 'git reset --hard HEAD@{1}'
