Branching and Merging Code with Git Source Control

When using Git for source control and versioning, the ability to branch that repository while you make changes off the mainline is key. However, eventually, that branch will need to rejoin the master branch and you will need to perform a merge. In this activity, the student will get an opportunity to perform a branch and then learn how that branch differs from the master, how they can move back and forth between the branch and master and finally, how to merge it back into mainline.
