Pull/Merge Requests refer to the process of submitting changes made to a Git repository to the owner of that repository for review and eventual incorporation. It is a specialized skill that involves creating a new branch, making changes, and submitting a request to have those changes merged with the original codebase. The process often includes detailed documentation, testing, and communication between team members. It is an essential part of collaborative software development and enables teams to work together to create high-quality code.
