Working in a team? Most commercial programming is done in teams To simplify project management and enforce accountability, version control is used

What is revision control? WITHOUT If a team creates a bug, it could affect how your code too You could loose old code or features that were removed Anyone could add bugs/features to a project and no one would know WITH You are isolated on your own branch, so you know who did it You can go back and see all old version of your project Someone has to approve your code submission

Lingo The Basics Repository – the database holding your code Main/Trunk – This is the primary code Working set – A file you checked out Tags – the name of the project stage Actions Check out – a downloaded file Check in – uploading the file Update – synchronizes your code Revert – toss the changes you made More complicated Branch – create a separate copy of a file or folder Diff – (I bet you know) Merge – combining branches

But how does one “branch”?

That’s how Linux is made (kinda)
