The document is a presentation on introductory concepts and workflows for Git and GitHub. It covers the history and goals of Git, key concepts like version control, repositories, and snapshots. It then demonstrates basic Git workflows like configuring user information, initializing a repository, adding and committing files, viewing differences between commits, and branching. Resources for continuing to learn Git are provided at the end.

● Git is a free and open source distributed Version
Control System
● Can handle small to very large projects with speed
and efficiency
● Created by Linus Torvalds, launched April 7 2005
● Every Git working directory contains a repository
with complete history and full revision capabilities
● Git is local , not dependant of a network or a
central server

9. (GDSC BMC)
@angeloseby | #gdscbmc
Goals of Git
● Speed
● Non - linear development / Parallel branches
● Fully distributed
● Able to handle large projects efficiently

@angeloseby | #gdscbmc
git --help
@angeloseby | #gdscbmc
Git’s
documentation
is built in - try it
for yourself

16. (GDSC BMC)
@angeloseby | #gdscbmc
Setup the
workspace
@angeloseby | #gdscbmc
Make a folder
named ‘project’
in desktop of
your system
$ mkdir project // Make new folder
$ cd project // Change directory
c:/desktop/project> $
Goto Desktop -> Right Click -> Open Terminal Here

17. (GDSC BMC)

If such branch doesn’t exist, creates a new branch with that name from the current
working branch

31. @angeloseby | #gdscbmc
@angeloseby | #gdscbmc
