# Usage:
#
# $ ./btrix bootstrap
# Build frontend and backend and upgrade
# Optional args:
#   -microk8s: Preface kubectl/helm commands with microk8s
#   -wait: Wait until pods are ready
#
# $ ./btrix reset
# Uninstall, delete data, then bootstrap
# Optional args:
#   -microk8s: Preface kubectl/helm commands with microk8s
#   -wait: Wait until pods are ready
#
# $ ./btrix down
# Uninstall and delete data
# Optional args:
#   -microk8s: Preface kubectl/helm commands with microk8s
#
# $ ./btrix test
# Run backend tests
#
# $ ./btrix nightly
# Run nightly backend tests
