Merge Conflict? Here’s Exactly What Happens — and How to Fix It Step by Step

Merge conflicts are common in software development even for experienced developers.
When two developers make changes to the same file in different branches, a merge conflict can occur when merging the changes back to the main branch.
To resolve a merge conflict, developers need to manually edit the file, choose which changes to keep, delete conflict markers, mark the conflict as resolved, and finalize the merge.
