  hs init                      (connect your HubSpot account)
  hs upload webocreation-marketing webocreation-marketing
Keep the templates/ and modules/ folders side by side: templates load modules with path="../modules/...".

Install without the CLI
  Design Manager > create a folder "webocreation-marketing" with subfolders "templates" and "modules".
  Create each module (File > New file > Module), add the fields from fields.json, paste module.html.
  Create each template (File > New file > HTML + HubL > Email or Page template) and paste the file.

Then
  Settings > Content > Brand / Account defaults: fill in your company name and address (the email footer reads them).
  Create an email or landing page and pick the "Webocreation - ..." template.
