Make sure you've already done the Github forking exercise.
Make your commit history look like this:
where the Added cheese commit adds a file called cheese.c with these contents:
the Added simpsons commit adds a file called simpsons.c with these contents:
and the Added my own dogs commit adds new dog types to the bottom of dog.c.
Added my own dogs
NOTE: Your commit hashes will be different from mine--this is because the commit hashes take time and name and email into account.
Once your commit history looks like this, push your master branch to github.
git push origin master
You may find the git commit --amend command useful to edit an existing commit (in case you mess up).
git commit --amend
