Triggering Pipelines:
- Pipelines can be triggered by various events.
- Rules can be set to determine if an event should initiate actions.
Defining Pipeline Rules: Use the rules key under the top-level workflow key to define rules for the entire Pipeline.
```
workflow:
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
```

Defining Job Rules: The rules keyword can also be used for individual jobs.

job1:
  script:
    - echo "This is a merge request"
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
