Push commits from a local repository to a remote repository.

Create a new repository in Github

1. In github.com, create a new repository, make sure you initialize it with a readme.
2. Clone your new repository to your computer
3. Open the folder that you cloned in atom.
4. Change the contents of the readme file. It does not matter what you changes, as long as it is different.
5. Add your changes to the staging area.
6. Commit your changes to a new revision
7. Push your changes to github.com
8. In github.com, go look at the file you change in your repository. Make sure that you click on the README.md file.
9. Click the commits link at the top of the text area, what do you see?

Create a repository on your computer first, that create a Github repository

1. In your computer, create a new folder named superProject
2. Change directories into your new folder
3. Initialize a new git repository.
4. Create a new file named README.md
5. Insert some text into README.md
6. Add your changes to the staging area
7. Commit your changes to a new revision
8. Go to github.com
9. Create a new repository name superProject, make sure that you do not initialize it with a README.md
10. After creating an empty repository, you'll get directions on how to associate your repository on your computer to the github repository. It will look as follows (Note: This is what I got, your text will be different):

git remote add origin https://github.com/rogerwschmidt/superProject.git
git push -u origin master

The first command adds a remote (In this case, github) to the local repository. The second command associates my local master branch, with the remotes' master branch

1. Run both commands in your terminal. Make sure that you run the commands from the folder in which your git repository was initialized.
2. Go back to Github.com to see your changes.
