The basic git workflow involves:

• Making changes to your source code/files
• Adding these changes to your staging area
• Commit the changes in your staging area to your repository
• Push your changes to a remote server
• Pull changes from the remote server, if necessary

In your terminal, cd into the directory in which you cloned your git repository, and open the README.md file with nano:

nano README.md

Make some changes to this file - for example, you might add a line or two of explanation.

At this point, if you run

git status

it should show that there are modified files. To add the changes to your staging area, run

git add README.md

and to verify, run

git status

To actually commit these changes to your repository, use

git commit -m "Commit message"

Now the changeset is committed to your local repository, but not in your remote repository yet. Verify this with

git status

To push your changes to the remote repository, run

git push origin master

and supply your Github username and password when prompted.

When a change exists in the remote repository but not in your local copy, you will use git pull to get it. Try editing the README.md file directly on the Github web interface (the remote); click on the file, then use the pencil icon to open it in edit mode. Make some changes and commit them from your browser. Then, in your local repository, run

git pull origin master

then

cat README.md

to verify that you have the latest copy of the file.
