config.yml

# This is a CircleCI configuration that you can add to your Github repository,
# and connect to CircleCI to generate your bioschema files! If you don't
# define any custom variables, your files will be generated and available
# as artifacts. If you define the GITHUB variables for a bot, we can put
# them back to Github Pages for more programmatic use (and version control
# archive)

# Variables you can customize
# OPENBASES_CONTAINER: is the container that will be used, see default section

# The following variables are optional and will give you
# additional deployments / functionality.

# GITHUB_USER
# GITHUB_EMAIL if defined, you can deploy your archive and site back to Github pages.
# REPO_VERSION: derived from the sha, for naming the archive
