Version control is the practice of managing and sharing changes to documents, programming code, websites or any other files to keep track of what’s been changed, by whom, when and why. All previous versions of files are saved and you can even revert to a previous version. Git is a version control software.
Git-portal sites, like GitHub or GitLab, offer many useful features to facilitate collaborative development.
This beginner level session will introduce you to Git. We will show you how to create a repository, record changes to files, explore and restore from the recorded history and how to resolve conflicts (when one member overwrites another’s changes).
