  summary _("Retrieve and store facts.")
  description <<-'EOT'
    This subcommand manages facts, which are collections of normalized system
    information used by Puppet. It can read facts directly from the local system
    (with the default `facter` terminus).

  find.returns <<-'EOT'
    A hash containing some metadata and (under the "values" key) the set
    of facts for the requested node. When used from the Ruby API: A
    Puppet::Node::Facts object.

    RENDERING ISSUES: Facts cannot currently be rendered as a string; use yaml
    or json.
  EOT
  find.notes <<-'EOT'
    When using the `facter` terminus, the host argument is ignored.

    summary _("Upload local facts to the puppet master.")
    description <<-'EOT'
      Reads facts from the local system using the `facter` terminus, then
      saves the returned facts using the rest terminus.
    EOT
    returns "Nothing."
    notes <<-'EOT'
      This action requires that the puppet master's `auth.conf` file
      allow `PUT` or `save` access to the `/puppet/v3/facts` API endpoint.

      For details on configuring Puppet Server's `auth.conf`, see:

      <https://puppet.com/docs/puppetserver/latest/config_file_auth.html>

      For legacy Rack-based Puppet Masters, see:
