Make the git repo part of the drupal site so I can commit my changes whilst testing
I found that if I cd into the profiles folder on the Drupal site that has been installed as above, and then commit changes, and push them to git, it also works as if I was committing them from the folder on the desktop which I initially ran the git init on. I read something that said that Drush automatically knows that you are in the directory of a Drupal install, so perhaps this is the resolution.
