Git & Github

Git and Github

What is Git.

Git is an Open Source Version Control System for management and development of projects. It was developed by Linus Tovalds and initially released on 7th April, 2005. Git is written in C, Python, Perl, Tcl and Shell Script.

It is a Distributed platform, that is, repositories can be accessed remotely. This provide an ecosystem where multiple developers can manage or develop a single project.

Why Git?

Using Git is pretty wonderful, infact, there are many reasons for developers to use Git. 

1.Git is almost cross platform, working on most platforms such as Windows, Linux and Mac OS.

2. It is Open Source under the GNU Public Licence.

3. It provide an ecosystem for multiple developers to collaborate on a single project, thereby providing a better project.

4. It helps developers in getting contribution from the public, i.e. Version Control System provide a chance for others to fork the project repository and work on it.

5. Helps in working on different versions of the same project. Developers can branch the project and work on multiple versions as possible as they can, later on they can merge it to a single project.

6. Larger companies such as Google, Microsoft and Facebook uses Git.

How to Install Git.

Git can be installed on your computer in two ways:

1. By downloading the software from the Git official website and download the version complatible with your platform.

After installing Git, you can run "git --version" in command line (Windows) or terminal (Linux or Mac OS). If you don't see any versions of Git, you can rerun the Setup or download a compatible version.

2. By installing commander, a command line tool which comes with Git preinstalled.

Github
