Where are the configuration files and scripts for CI/CD automation usually located in a project?

Configuration files and scripts for CI/CD automation are usually located in the root of the project or in a specially designated directory, for example:

• In the project root: files like .gitlab-ci.yml, .github/workflows/, Jenkinsfile.
• In folders such as ci/, build/, scripts/ — for auxiliary scripts and configurations.

This arrangement allows CI/CD systems to automatically find and use these files during the build, testing, and deployment of the project.

Example:

my-project/
├── src/
├── scripts/
│   └── deploy.sh
├── .gitlab-ci.yml
└── Jenkinsfile
