Merge branch 'master' of https://github.com/apelade/gitimmersion
I had already created this repo on github and had to add one commit
 for the test git ls to find it, then switched to octokit in the test
 which may have found it anyway. Then started the tutorial set that
 as my origin and now pushing so there is an extra commit at the
 beginning, of the Readme.
