+Browser Compatibility
+---------------------
+
+Raven.js supports all major browsers. In older browsers, error reports collected
+by Raven.js may have a degraded level of detail – for example, missing stack trace data
+or missing source code column numbers.
+
+The table below describes what features are available in each supported browser:
+
++-------------------------+--------------+----------------+-------------+
+| Browser                 | Line numbers | Column numbers | Stack trace |

+For unlisted browsers (e.g. IE7), Raven.js is designed to fail gracefully. Including
+it on your page should have no effect on your page; it will just not collect
