Answer (EN)

**Continuous Integration (CI)** is a development practice in which **code from all branches is regularly merged into the main one**, and then **automatically checked and tested**.
The core idea is to **catch errors as early as possible**, while changes are still small and understandable.

### How CI works

1. The developer makes a commit and pushes the code to the repository.
2. The **CI server** triggers (for example, GitHub Actions, Jenkins, GitLab CI).
3. It automatically runs:
  - the project build;
  - the tests;
  - linting and code quality analysis;
  - security and dependency checks.
4. If something fails, the developer gets a notification and quickly fixes the error.

### Goals of CI

- **Early stability checks** - errors are caught right after the commit.
- **Conflict-free integration** - frequent merges prevent "merge hell".
- **Faster development** - automation removes the routine of testing and building.
- **Quality assurance** - code will not enter the main branch until it passes all checks.

### Example

Every pull request automatically triggers a pipeline:
→ build, → tests, → status report.
If all checks are green, the PR can be merged.

### Conclusion

**Continuous Integration** is the project's automated "watch post":
it guarantees that new code is **immediately checked, compatible, and does not break the system**,
creating the foundation for stable and fast development.
