# This is a bootstrap only: it installs the NerionX CLI, which owns the actual
# setup (`nerionx init` scaffolds the kit, `nerionx up` runs it).
#
# It deliberately downloads no compose file, env template, or provision script.
# Those ship inside the CLI package, version-locked to the CLI that reads them.
# Serving copies from here is what let this installer drift out of sync with the
# repo and hand brands a kit that could not boot (no SETTINGS_ENCRYPTION_KEY).

Next — create your Brand Kit (use the slug and API key issued to your brand):

  mkdir my-brand && cd my-brand
  nerionx init --slug my-brand --hub-api-key nx_live_...
  nerionx up

  nerionx status          # container status
  nerionx logs spoke -f   # tail the Spoke

  Spoke admin → http://localhost:9001/app
  Storefront  → http://localhost:8000
