What we'll cover
 Concept of Version control system
 Concept of Git
 Some basic commands

Version control
Most used Concurrent version system(CVS) and
Subversion(SVN).
Key concepts:
 Central source control system
 users check code into server
 requires connection to the server to perform
commits, updates etc.

Git????
• Distributed Version Control System
• Like sub-version but better...
• Created by Linus Torvald

Why Git???
• Distributed repository
• Self contained
• Full history of commit
• You can commit/branch/merge locally
• Read fast and offline
• No "latest revision": revision unique ID

with git :
# git init
You’ve now created your ﬁrst git repository!
For remote repository access:
# git clone remote_git_repository_url Example:
# git clone git@github.com:mobbazaar/api

Useful basics commands
git init repository setup
git add add files to queue for next commit
git commit commit queued files
