tutorials create a repository in github, insert a file, and make a comment

GitHub is an online VCS which is very useful for those who work in a team or own. GitHub is now widely used by developers to manage the project files they are running both in teams and individuals.
GitHub is a VCS that already uses the GUI so it makes it easier to manage the files. There are also some additional features in GitHub that are interesting so that its interface is very convenient to use.
Imagine if you work on a team in a project. when you make a change and your team does not know then the project you build will be a mess. Or you can inform the changes you make through SMS, Line, or other social media. But it's all ineffective.
With an online VCS or remote repository, team members are only logged in and logged into the repository so they can see the changes you are making, as VCS notifies any changes made.
Big companies like teamtreehouse, facebook, and twitter also use VCS to organize or manage their files. It's just that the VCS they use is made private so only certain people can see. In the job interview also if you can use VCS either command line or GUI especially GitHub then you will be a choice to be considered more than others who do not understand VCS.
