In order to commit your changes GIT requires that you set two variables:
user.name - Your name i.e. “Joe Blogs”
user.email - Your email i.e. mary.Jones@life.com
These can be set at the command line of GIT, like so:
git config --global user.name "Mary Tyler Moore" git config --global user.email "mary@moore.com"
The GIT setup screen also allows one to set these parameters.
These parameters are different from the credentials required for your cloud host.
