Purpose Of Using Git

1. Suppose there is 3 people (x,y & z) together working on a project called "foobar".
2. Project "foobar" has a central repository with developer x (or hosted on GitHub.com)
3. Developer y & z does "Git clone" once to create a local copy of project "foobar"
4. Developer y & z everyday in morning (or whenever they start developing work) do "git pull" to get all the latest update of the project "foobar" from central repository, Now they will start working on the latest copy of the project
5. At night (or when they finish developing work) all 3 i.e x, y & z performs "git push" to make changes on the central repository saved at workstation of developer x (or at GitHub.com).

Some usefull commands

1. Git clone URL:
2. After you have done a git clone, you have a copy of the complete repository.
3. Make some changes to the local version of the repository, then git add and git commit the changes to the local repository.
4. Git push to publish the changes (“commits”) to the remote repository
5. Periodically git pull to retrieve any new updates from the remote repository.
