# DO NOT EDIT THE RENDERED SCRIPT
# Instead, update the j2 template, and regenerate it for dev with `make render-docs`.

# The getting started guide script
# It uses tagged regions which are included in the documentation
# https://docs.asciidoctor.org/asciidoc/latest/directives/include-tagged-regions/
#
# There are two variants to go through the guide - using stackablectl or helm
# The script takes either 'stackablectl' or 'helm' as an argument
#
# The script can be run as a test as well, to make sure that the tutorial works
# It includes some assertions throughout, and at the end especially.
