-# This is a sample GitLab CI/CD configuration file that should run without any modifications.
-# It demonstrates a basic 3 stage CI/CD pipeline. Instead of real tests or scripts,
-# it uses echo commands to simulate the pipeline execution.

-# A pipeline is composed of independent jobs that run scripts, grouped into stages.
-# Stages run in sequential order, but jobs within stages run in parallel.
