Configuration

CircleCI believes in configuration as code. Your entire CI/CD process is orchestrated through a single file called config.yml. The config.yml file is located in a folder called .circleci at the root of your project that defines the entire pipeline.

Example of a directory setup using CircleCI:

├── .circleci
│   ├── config.yml
├── README
└── all-other-project-files-and-folders

Your CircleCI configuration can be adapted to fit many different needs of your project.

Here are the most important terms you should know:

• Pipeline: Represents the entirety of your configuration.
• Workflows: Responsible for orchestrating multiple jobs.
• Jobs: Responsible for running a series of steps that perform commands.
• Steps: Run commands (such as installing dependencies or running tests) and shell scripts to do the work required for your project.
