      {
        using( var doc = DocX.Load( fs ) )
        {
          // Add a title
          doc.InsertParagraph( 0, "Load Document with Stream", false ).FontSize( 15d ).SpacingAfter( 50d ).Alignment = Alignment.center;

          // Insert a Paragraph into this document.
          var p = doc.InsertParagraph();

          // Append some text and add formatting.
          p.Append( "A small paragraph was added." );

          doc.SaveAs( DocumentSample.DocumentSampleOutputDirectory + @"LoadDocumentWithStream.docx" );
        }
