5. Version control is a system that keep records of all

helps us to switch back to any version.
What is VCS?

6. Why use GIT?
-Store revisions in a project history in just one directory
-Rewind to any revision in the project
-Work on new features without interference of main codebase
-Easily collaborate with other programmers

7. What is GitHub?
-Online service that hosts our projects
-Share our code with other developers
-Developers can download the projects and work on them
-They can re-upload and merge their edits to the main codebase

8. Terminology we use
Directory -> Folder
Terminal -> Interface for Text commands
CLI -> Command Line Interface
mkdir -> Creates a new folder
cd -> Change directory

Branch-

16. Basic Git Commands
git init- to initialize git and make a .git repository
git rm[file]- deletes the file from your working directory
git status- gives you the status on your local branch
git add- adds the file to staging area
git commit- to commit the staged files
git clone- downloads repository from GitHub to your system
git push- sends local files to remote branch
git branch- lists available local branches and can create a new
branch
git merge- to merge branches together
