Using GIT – Introduction

Git is essentially a version control system for tracking changes in computer files. This can be used in conjunction with Visual Studio to program in C#, for example. Git can be accessed through commands through the command window in windows. Git is generally to coordinate changes to code between multiple developers and is also used to work in a local repository which is then “pushed” to a remote depository such as

Git tracks changes to files by taking snapshots. This is done by the user by typing “git commit ….” in the command prompt. The files should be added to the staging area first by using the command “git add <filename>”. “Git push” and “git pull” are used to interact with the remote repository. “Git clone” will copy and download a repository to your local machine. Git saves every version that gets committed, so a previous version can always be accessed if necessary. The following image illustrates the concept of committing.


You can essentially “branch” your commits which can later be merged together by using “git commit” command with multiple parents. The master branch is the main/linear list of saves. This can be done in the remote repository or the local. A “pull request” essential means taking changes that were made in a certain branch and pulling them into another branch. This means multiple people can be editing multiple branches which can then be merged together.

Git is extremely useful for collaboration (as with websites such as google docs) where multiple authors can work on something at the same time. It also is excellent for keeping track of the history of projects.
