Prerequisite steps could be automated

[mattysweeps]

The manual prerequisite steps could be (mostly) automated if we know the domain name and the availability zone.

• quota checking
• DNS verification
• DNS zone creation

Output: we could create a ./verify.sh or similarly named script which performs the prerequisite steps.

The process would be checking if the domain name (must be provided) resolves, and if it doesn't, inform the user to add the correct NS record to their DNS records.
