What does "pull request" mean?

A Pull Request (PR) is a request to merge changes from one branch into another (usually from a feature branch into main or develop). It is the main tool for code review and collective quality control in Git projects.

#How it works

1. A developer creates a new branch, makes commits, and pushes it to the repository.
2. Once the work is done, they open a pull request in the system (GitHub, GitLab, Bitbucket).
3. In the PR, they provide:

• a description of the changes,
• related tasks or tickets,
• possible risks.

4. Colleagues (reviewers) check the code, leave comments, and suggest fixes.
5. After the fixes and approval, the PR is merged into the target branch.

#Why it is needed

• for code review before code is merged;
• for transparency of changes - it is visible who made a change and why;
• for automatic checks (CI runs tests on every PR);
• for documenting the development history.

#Example

A developer opens a PR:

"Added an API for user registration (#123)" Colleagues review it, the tests pass, the PR is approved and merged into develop.

#Conclusion

A pull request is a "checkpoint" between writing code and integrating it. It combines review, testing, and discussion, ensuring a high-quality and safe merge of changes.
