# Azure pipelines for Marian NMT
#
# The pipeline need to be added manually to the repository, for example:
# 1. Go to Your repository > Pipelines, click "New pipeline"
# 2. Choose "Azure Repos Git" and a repository
# 3. Choose "Existing Azure Pipelines YAML file" and specify path to this file
# 4. "More actions" > "Save"

parameters:
# Allow skipping the entire 'Build' stage
- name: runBuilds

  type: boolean
  default: true

# The pipeline CI trigger is set on the branch master only and PR trigger on a
