Initializing a repository

$ git init

// get everything ready to start git writing

1. make git directory: first_git_project

2. in cmd line

 - $ cd Documents/first_git_project

 - $ git init // things in this directory are things to be aware of

// "Hey Git, this is the directory you need to track of"

// .git file should be inside the repository because it can make tracking

ls -la .git //leave it alone..
