Hey @creativemine!
You don’t have to utilize the CMS before publishing. If you have no need for it now, you can wait until you have a use for it and then add it in easily by creating a Collection (how the CMS items are stored and organized) in the CMS tab of the Designer.
On a similar note, if you don’t need to use the CMS, you likely can get away with the Basic hosting plan (instead of CMS Hosting) and then upgrade accordingly if you need it.
If you have any questions, feel free to reply back or private message me and I’d be happy to point you in the right direction.
