-# This file is a template, and might need editing before it works on your project.
-# 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.
-#
-# For more information, see: https://docs.gitlab.com/ee/ci/yaml/index.html#stages
-#
-# You can copy and paste this template into a new `.gitlab-ci.yml` file.
-# You should not add this template to an existing `.gitlab-ci.yml` file by using the `include:` keyword.
