  The `~certbot_dns_nsone.dns_nsone` plugin automates the process of completing
  a ``dns-01`` challenge (`~acme.challenges.DNS01`) by creating, and subsequently
  removing, TXT records using the NS1 API.
  
  
  Named Arguments
  ---------------
  
  ========================================  =====================================
  ``--dns-nsone-credentials``               NS1 credentials_ INI file.
                                            (Required)
  ``--dns-nsone-propagation-seconds``       The number of seconds to wait for DNS
                                            to propagate before asking the ACME
                                            server to verify the DNS record.
                                            (Default: 30)

  Credentials
  -----------
  
  Use of this plugin requires a configuration file containing NS1 API credentials,
  obtained from your NS1
  `account page <https://my.nsone.net/#/account/settings>`_.
  
  .. code-block:: ini
     :name: credentials.ini
     :caption: Example credentials file:
  
     # NS1 API credentials used by Certbot
     dns_nsone_api_key = MDAwMDAwMDAwMDAwMDAw
  
  The path to this file can be provided interactively or using the
  ``--dns-nsone-credentials`` command-line argument. Certbot records the path
  to this file for use during renewal, but does not store the file's contents.
  
  .. caution::
     You should protect these API credentials as you would the password to your
     NS1 account. Users who can read this file can use these credentials to issue
     arbitrary API calls on your behalf. Users who can cause Certbot to run using
     these credentials can complete a ``dns-01`` challenge to acquire new
     certificates or revoke existing certificates for associated domains, even if
     those domains aren't being managed by this server.
  
  Certbot will emit a warning if it detects that the credentials file can be
  accessed by other users on your system. The warning reads "Unsafe permissions
  on credentials configuration file", followed by the path to the credentials
  file. This warning will be emitted each time Certbot uses the credentials file,
  including for renewal, and cannot be silenced except by addressing the issue
  (e.g., by using a command like ``chmod 600`` to restrict access to the file).
