# Deployed to: https://github.com/stellar/stellar-docs

# Converted from the Jenkins pipeline (Jenkinsfile-stellar-docs). On every push
# to main (or manual dispatch) builds the stellar-docs docker image (with
# translations), pushes it to the prd ECR repo (prd/stellar-docs:<sha>), and
# also pushes it as dev/stellar-docs:latest for PR previews.
