With multi-line statements, I think it'd look better if we left-indented the closing `PCDESC` with the opening `description`:

      description <<-PCDESC
        This resource allows for the management of patient records in the popHealth application.
        ...
      PCDESC

 I know you'd need to put `PCDESC` at the beginning of the line if you did `description <<PCDESC`, but not with the `-`, which you have.
