Git Pull Request (PR): Complete Process for Initiating a PR on GitHub

GitHub PR is a method for developers to submit code changes to the main branch, facilitating code review, historical record, and standardized collaboration. Before initiating a PR, local preparation is required: commit modifications (`git add . && git commit`), synchronize with the main branch (merge main branch code to avoid conflicts), and confirm the commit status. When creating a PR on GitHub, select the target branch (Base) and the modification branch (Compare), fill in the title and description, and link the PR to an Issue. The PR must undergo review and feedback for revisions, and after approval, it is recommended to use "Squash and merge" to keep the history concise. After merging, delete the source branch and synchronize locally. Pay attention to branch naming conventions, small and focused PRs, clear commit messages, and conflict handling. PR is a crucial part of team collaboration and code quality assurance.
