 Using Skia's PDF Backend
 ========================
 
 Here is an example of using Skia's PDF backend in the recommended way:
 via the SkDocument and SkCanvas APIs.
 
 <!--?prettify?-->
 
     #include "SkDocument.h"
 
     bool WritePDF() {
-        SkWStream* output = ....;
+        SkWStream* outputStream = ....;
 
         SkAutoTUnref<SkDocument> pdfDocument(
                 SkDocument::CreatePDF(outputStream));
 
         int numberOfPages = ....;
         for (int page = 0; page < numberOfPages; ++page) {
             SkScalar pageWidth = ....;
             SkScalar pageHeight = ....;
             SkCanvas* pageCanvas =
                     pdfDocument->beginPage(pageWidth, pageHeight);
 
             // ....insert canvas draw commands here....
 
             pdfDocument->endPage();
         }
+
+        SkTArray<SkDocument::Attribute> info;
+        info.emplace_back(SkString("Title"), SkString("...."));
+        info.emplace_back(SkString("Author"), SkString("...."));
+        info.emplace_back(SkString("Subject"), SkString("...."));
+        info.emplace_back(SkString("Keywords"), SkString("...."));
+        info.emplace_back(SkString("Creator"), SkString("...."));
+        SkTime::DateTime now;
+        SkTime::GetDateTime(&now);
+        pdfDocument->setMetadata(info, &now, &now);
+
         return pdfDocument->close();
     }
