This 6-video course is the first in a 3-course series that explores the concepts of version control systems in general and the popular control system Git, an open-source version-distributed system which tracks changes in source code during software development. The course covers the web-based platform GitHub, which simplifies team collaboration when sharing source code. Participants will examine the features of control systems and learn to use Git repositories to track the desired project source code. Since Git is designed to coordinate work among programmers, this course explores branching and merging the code developed by a team. You will learn how teams can develop code collaboratively when building features for an app, by using branches in Git. This course demonstrates the feature branches used to merge code into the main master branch of a Git repository. Learn to identify merge conflicts. Finally, you will explore GitHub which supports all popular programming languages by demonstrating the features GitHub uses to manage Git repositories, and how GitHub assists in streamlining the iteration process.
