4. Version control systems
• Version control is a system that records changes to a file or set of
files over time so that you can recall specific versions later.
• Version control (or revision control, or source control) is all about
managing multiple versions of documents, programs, web sites, etc.
 Almost all “real” projects use some kind of version control
 Essential for team projects, but also very useful for individual projects
• Some well-known version control systems are CVS, Subversion,
Mercurial, and Git.

5. Lets say you have a project you want to work on.
Now you have 2 primary motives.
(a) To write some code
(b) To take up the project as a team , meaning that more than one people are going to be
responsible for writing the code.
User 1 User 2
Hello World !

Hello World !

User 1 User 2
Hello World !
copy
Hello World !Hello, I am
awesome

7. Here User 2 change the code, now at this point User 1 wouldn't
know the changes User 2 have been made and User 1 start coding
further with his code which lead to wrong results.
User 1 User 2
Hello World !
copy
Hello, I am
awesome

8. What is Git & Github ?
Git:
Git is an example of version control
It allows you to :
• Save your code online.
• Git will allow all the developers of a project to see what changes the other one has
made.
• It allows you to discuss issues in your code with other developers.
And a lot more...

Hello World ! Hello World !Git

11. What is Git & Github ?
Github:
Github is a repository hosting service for Git based on “Ruby on
Rails”.
• While Git is a command line tool, GitHub provides a web-
based graphical interface that works on top of GIT. It can also
be treated as a social platform to share knowledge and work.
• It also provides access control and several collaboration
features, such as wikis and basic task management tools

12. History of Github
• Founded in 2008 by Tom Preston-Werner
• Funding 0$
• At that time 46 Employees with no middle managers; in other words, "everyone is
a manager" (self-management).Employees can choose to work on projects that
interest them (open allocation).
• And Now 467 Employees.
• 30+ Million Repositories
• 10+ Million Users

13. Concepts for Github Users
• Repository : A repository is a folder inside which you are going to store
every piece of your code.
• Fork : Copying someone's repository into your account is called forking.
• Upstream : The guy or organisation which owns the code that you forked.

14. Understanding Github Workflow
• First of all – create a Github Account
• And second :

15. Github Desktop Demo
We can create repositories by two methods :
• Github GUI Software
• Git Windows PowerShell

16. DEMO TIME
• Create a Github account
• Set up with Windows

• Fork a repository
• Delete a repository
