+Testing
+=======
+
+Skia relies heavily on our suite of unit and Golden Master \(GM\) tests, which
+are served by our Diamond Master \(DM\) test tool, for correctness testing.
+Tests are executed by our trybots, for every commit, across most of our
+supported platforms and configurations. 
+Skia [Gold](https://gold.skia.org) is a web interface for triaging these results.
+
+We also have a robust set of performance tests, served by the nanobench tool and
+accessible via the Skia [Perf](https://perf.skia.org) web interface.
+
+Cluster Telemetry is a powerful framework that helps us capture and benchmark
+SKP files, a binary format for draw commands, across up to one million websites.
+
+See the individual subpages for more details on our various test tools.
