Understand the concept of a Pull Request for proposing and reviewing changes.
A Pull Request (PR) is a feature of hosting platforms like GitHub, not a core Git command. It is the primary mechanism for collaboration. A PR is a way of telling others about changes you've pushed to a branch in a repository on GitHub. Once a Pull Request is opened, you can discuss and review the potential changes with collaborators and add follow-up commits before your changes are merged into the main branch. The typical workflow is: you push your new feature branch to the remote repository, then go to GitHub and open a Pull Request to merge your feature branch into the `main` branch. This kicks off a code review process. Your teammates can comment on your code, request changes, and discuss the implementation. Once the PR is approved, it can be merged into the `main` branch directly through the GitHub interface. This workflow ensures code quality and provides a clear history of decisions made about the project.
