git

phase 1st:

　　in order to do anything in git, you must have a repository which is where git stores the data for the snaphshots you are saving.

two common ways to get a git repository:

　　 initialize a new one from an existing directory , such as a new project or project new to source control.

　　the second way is to clone one from a pulbic git repository . ( if you wanted a copy or wanted to work with someone on a project.)

 

now i will cover the first way ,then the second way

　　turn to a working directory:    

　　　　such as :    cd  konnichiwa      ( there are two files : README     hello.rb)

　　　　　　　　　　ls

　　　　　　　　　　　　README   hello.rb

          then  run the command:        git init

　　　this command will create a new subdirectory  :  .git ,      (this directory is your Git repository where all the data of your project snapshots are stored.)

　　 after these steps . now you can start snapshotting your project.

 

Second way to create git repository:   git clone    (copy a git repository so you can add to it)

　　　run command:    git  clone [url]                (the url reffers to the projrct which you want to copy.)
