Git will determine the merge algorithm automatically (discussed below). Invoking this command will merge the specified branch feature into the current branch, we'll assume main. We now want to merge this feature branch into main. Say we have a new branch feature that is based off the main branch. Once Git finds a common base commit it will create a new 'merge commit' that combines the changes of each queued merge commit sequence. The following examples in this document will focus on this branch merging pattern. In these scenarios, git merge takes two commit pointers, usually the branch tips, and will find a common base commit between them. Git merge will combine multiple sequences of commits into one unified history. In the most frequent use cases, git merge is used to combine two branches. Again, this means that git merge is often used in conjunction with git checkout for selecting the current branch and git branch -d for deleting the obsolete target branch. The current branch will be updated to reflect the merge, but the target branch will be completely unaffected. Note that all of the commands presented below merge into the current branch. The git merge command lets you take the independent lines of development created by git branch and integrate them into a single branch. Merging is Git's way of putting a forked history back together again.

Easy doc merge by my way
