Git concepts: pulling

Pulling in Git refers to the process of fetching changes from a remote repository and merging them into your local repository. The 'git pull' command is essentially a combination of 'git fetch' followed by 'git merge'.

When you execute 'git pull', Git will update your local working branch and its corresponding remote tracking branch. After 'git pull' is executed:

Git fetches updates from the remote repository, adding commits to your local repository that are present in the remote repository but not in your local repository.

Git then merges the fetched updates into your current branch. If the branch you're currently on is tracking a branch in the remote repository, Git automatically knows which server to fetch from and branch to merge into.

If any conflicts arise between the local and remote repository during a 'git pull', they need to be resolved manually.

In summary, 'git pull' is a command used to update the local version of a repository from a remote. It fetches the remote data and merges changes into the local branch, helping to keep your codebase up to date.
