GIT

Create a sample.txt file Sample Folder.
In sample folder directory run command prompt
Run git init to initialise git in the directory

git init - working directory - git add - staging area - git commit - repository

Now track the text file with git add sample.txt to track the file.
Tracked file changes can be seen with git diff sample.txt
Differences are prefixed with + symbol


Now add the changes to staging are with git add sample.txt
Commit is the final step. Message is added along with a commit (50 Characters)
git commit -m "First Commit" command is used to staged files.
Commit logs can be seen with git log command.

Why Branch?
To have multiple version. (Happy ending, Sad Ending).
