Introduction
Git is a source code management technology used by DevOps. It is a free and open-source version control system that is used to efficiently manage small to extremely big projects.
Git is a version control system. Version control is a file manager that maintains track of changes to your projects over time and keeps a complete history of whatever you're working on. It allows many developers around the globe to work together on the same project at the same time
GitHub is a site that hosts Git repositories, but it also has a lot of its own features. It is a web-based graphical interface for Git, which is a command-line application. Each project has access control and numerous collaborative capabilities, such as wikis and rudimentary task management tools.
It is the home of 56 million ( September 2020 ) developers around the globe which is currently owned by Microsoft
Installation
Every operating system has its own steps to install Git, In this article, I will cover Linux, Windows, and Mac ( Which are the most popular ones )

Basic GitHub terms
- Fork: Fork is a copy of another user's repository that lives on your personal Github account. The major reason for this is to adapt other people's repositories to meet your needs.
- Main: When you create a new repository, it comes with a default development branch.
- Readme: It is a text file that contains information about other files in a repository. It is usually a basic plain text file called Read Me that serves as documentation.
- Repository: A Repository is a place where tour work will be stored in a directory or storage space. This is sometimes abbreviated as "repo" by GitHub users.
- License: If you want your repository to be genuinely open source, you'll need to license it so that others can use, modify, and distribute it.
- Pull request: It allows you to announce a change made by you in the branch. It is a way for a developer to let the rest of the team know when they've finished a feature.
Basic Git Command
-
git init: The git init command creates a new Git repository. Executing this command creates a.gitsubdirectory in the current working directory, which contains all of the necessary Git metadata for the new repository. -
git clone: The git clone command is used to create a copy of a specific repository or branch within a repository. -
git branch <branch-name>: This git command is used to create a new branch for a specific repository. -
git checkout <branch-name>: The git checkout command lets you navigate between the branches created by the git branch. -
git add: It is the first command in a chain of operations that directs Git to "save" a snapshot of the current project state, into the commit history. It is used to tracks your file and changes in Git -
git commit: The git commit command takes a snapshot of the current state of the project's changes. -
git push: This command is used to upload git commits to a remote repository like Github
The power of Open Source is the power of the people. The people rule. ~ Philippe Kahn

- To add your remote origin link, use the command below
git remote add origin main https://github.com/suhailkakar/demo
- To push your code to GitHub, you can use the below command
git push -u origin
GitHub special repository
GitHub offers a special repository by your username, which should contain a readme.md and it will show in your GitHub profile, just like mine
If you want a similar look, you can fork my repository here
