Update intro-github.md
changes made to the document: * Corrected the document title and sidebar_label from "Introduction of GitHub" to "Introduction to GitHub" for grammatical accuracy. * Rewrote the "Key Features" section to remove factually incorrect information (e.g., "Premium" plan, "Repo time") and replaced it with accurate features like collaboration tools and GitHub Actions. * Corrected the attribution for Git's creation to "Linus Torvalds," removing the incorrect "and Junior." * Fixed multiple technical inaccuracies in the terminology tables, clarifying the definitions for Branch, Fork, Hash, and Repo, and filled in a missing description for Remote. * Repaired the broken Markdown syntax for both tables, allowing them to render correctly. * Removed a broken, irrelevant hyperlink (to Visual Studio Code) that was wrapped around an image. * Replaced the non-functional placeholder URL in the YouTube iframe with a valid one. * Fixed numerous typographical errors (e.g., "repeitive") and grammatical mistakes (e.g., "it let's people," "want we do"). * Removed the redundant, repeated sentence in the "Conclusion" section.

GitHub is a web-based platform used for version control and collaboration. It allows developers to work together on projects from anywhere in the world. GitHub is built on top of Git, a distributed version control system created by Linus Torvalds in 2005.

## How to start with GitHub?

Whenever you create something exciting or something new on your own, you always want to show it to others. As programmers, we also want to show our projects and codes to others, but how? So GitHub is the solution, it let's people to collaborate and scale the projects all on cloud. Some other example of similar platform are Bitbucket, GitLab, Beanstalk, etc. Many of them give you the facility to work on your code together as a team. Currently, GitHub is more popular than other above-listed platforms for hosting your code.

In the picture below, you can see Developer 1, Developer 2, etc., working on the same project. Let's say they are trying to build an Amazon website; Developer 1 handles the men's shopping section, Developer 2 deals with the women's section, and Developer 3 works on the login feature.

So, each individual works on a different feature from a copy of the central repository, once the development is done they push changes to the *remote repository* (central repo as per picture). Once a code review happens and it is good to go, the senior developer will merge the code into the central repository so all the features will be live in production.

## What is Git??

In the above example, all the developers were able to work on different features simultaneously because of Git. For uploading your project to your GitHub account, you need to install Git first. In other words, Git helps with the version management of files and coordinates work among a diverse team in the software development phase. Git is an open-source project and developed in 2005 by Linus Torvalds and Junior.

1. *What is Version control System?*: To understand the version control system, let me give you one example; sometimes, you wish you have a record that contains all the changes you made in your code or your project. The version control systems are software tools that record all of your changes in the files. It is like a database of changes. Git is a version control system that most developers prefer to use. We will see how you can upload your code on GitHub using Git. With VCS you can track the branch, who made changes at what time, line of code added, retrieve the previous version of changes.

| VCS | Version Control System | Track changes to a collection of files |
55-
| SCM | Software configuration Management | Another name for VCS,earlier versions of VCS, like CVS and SVN, used a centralized server, which caused a single point of failure. |
56-
| DVCS | Distributed Version Control System| Git is distributed, the project history is stored both in client and server. Means you can make changes locally and remote. |
57-
| Working Tree | Tree | Current version of files where the active project is on |
58-
| Repo | Repository | Top of the working tree where Git keeps all records and history. |
59-
| Bare repo | | Not part of working Tree ends with .git, eg. backup.git |
60-
| Hash | 160 bit long SHA-1 | Based on the hash number, the file has been modified or not. |
61-
| Object | Git has 4 objects | Tree Object(directory, names), Blob Object(main file), Commit Object(specific versions), Tag(name attached to commit) |

| Commit | | Makes Changes |

62+
| Object | Git has 4 objects | **Blob** (file content), **Tree** (directory structure), **Commit** (a snapshot in time), **Tag** (a name attached to a commit). |
63+
| Commit | | A snapshot of the repository at a specific point in time. |
64+
| Branch | | A lightweight, movable pointer to a specific commit. `HEAD` is the pointer to your current branch. |

## Why Learn GitHub?

GitHub simplifies the command-line interface of Git and makes it more GUI-friendly. GitHub is built on top of Git. Here want we do is staging the files and doing the commit, You can clone the entire repository, create a branch, commit to that branch, and then ask the main developer to merge the branch. When you clone in reality you are creating a copy of the real code/repository in your local environment.

The fork is a personal copy of the repo which is already present or uploaded in GitHub by a different user. Once you fork and make changes to the repository the changes will happen to your forked repo, not the real one.
