yum install git

To set the default name and email globally for git to use when you commit:

git config --global user.name "username"
git config --global user.email "username@example.com"

To set the default name and email for a specific repository:

cd your_repository

Creating and Setting up a Repository
You can find the original guide here.
On the GitHub home page, click the "Create repository" button.

To setup a git repository you've created, follow the given steps below:
1. Go into the directory of an existing project or create a new directory for your project and go into it.
2. Initialize an empty git repository inside your project directory by executing "git init".
3. Create a README file inside your project folder and write a description in that file.
4. Add your files. The "git add" command puts your files into staging.
5. Commit your files.  Committing your files applies changes in your local repository.
6. Create a remote name "origin" pointing at your GitHub repo.
7. If you are using ssh, modify the url variable in the ".git" file or execute a command to set it.
8. Push your commits to your GitHub account.

cd /home/oracle/NetBeansProjects/[PROJECTNAME]
git init
touch README
git add *
git commit -m 'first commit comment';
git remote add origin https://github.com/[USERNAME]/[PROJECTNAME].git
git remote set-url origin ssh://git@github.com/[USERNAME]/[PROJECTNAME].git
git push --force origin master
