When you use Git to manage your code changes, you create a directory on your local computer for each branch that you wish to work with. This is in addition to the set files that exist at github.com.

• When you execute the git commands from the command line in the shell, you should have the current directory set to the root of the file system on your laptop.
• When you use an IDE such as Eclipse, you should not have the local files within the directory structure that the IDE uses by default. You will then specify the directory containing in the files within the IDE.

Once you have made changes to the files, the following procedure will move the changes to the copy at github.com.

• Set the current directory to the root of the file system for the branch.
• The command git add . will insure that all of the files are marked for management.
• The command git commit -a -m "my comments" will locate all of the modified files and mark them as committed. The text after the -m operator will become the message Git uses to describe the commit.
• To move all of the changes to the copy on github.com, you will execute the command git push origin branch where branch is the name of the branch to be processed. On my system, the branches are master for the project and gh-pages for the documentation.
