Version Control System

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.

Goals:

• Record edits
• Keep a change history
• Backup and restore
• Branching
• Ease of collaboration

Example software:

• GIT
• Subversion (SVN)
• CVS

GIT

• Distributed
• Open-source
• Scalable
• Fast
• Only stores differences between versions

Workflow

• Clone (copy to local computer)
• Modify/add/delete files
• Stage the files
• Commit locally
• Push changes to remote repository
   
• Pull to update local repository
