Complete Git Guide: Understand and Master Git and GitHub - Fetching Changes from Upstream

The video tutorial explains the concept of remote repositories in Git, focusing on 'origin' and 'upstream'. It demonstrates how to fetch changes from an upstream repository using the 'git fetch' command and view the fetched branches. The tutorial also covers actions that can be performed with these branches, such as checking out and merging them into local branches. Finally, it introduces the concept of syncing changes from the upstream master branch to the local master branch, which will be detailed in the next lecture.
