# This file is based a sample GitLab CI/CD configuration file that demonstrates a basic 3 stage CI/CD pipeline.
# This specific template is located at:

# 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
