# 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"

# The pipeline has no CI trigger and needs to be started manually, for example:
# 1. Got to the Pipeline created above
# 2. Click "Run pipeline" and select a "Branch/tag" you want to run it with
trigger: none
