+Welcome to the WebGL Conformance Test Suite
+===========================================
+
+Note: Before adding a new test or editing an existing test
+[please read these guidelines](test-guidelines.md).
+
+This is the WebGL conformance test suite. You can find a the current "live"
+version at [https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html](https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html)
+
+NOTE TO USERS: Unless you are a WebGL implementor, there is no need to submit
+a conformance result using this process.  Should you discover bugs in your
+browser's WebGL implementation, either via this test suite or otherwise,
+please report them through your browser vendor's bug tracking system.
+
+FOR WEBGL IMPLEMENTORS: Please follow the instructions below to create
+a formal conformance submission.
+
+1. Open webgl-conformance-tests.html in your target browser
+
+2. Press the "run tests" button
+
+3. At the end of the run, press "display text summary"
+
+4. Verify that the User Agent and WebGL renderer strings identify your browser and target correctly.
+
+5. Copy the contents of the text summary (starting with "WebGL Conformance Test Results") and send via email to
+   webgl_conformance_submissions@khronos.org
+
+Please see CONFORMANCE_RULES.txt in this directory for guidelines
+about what constitutes a conformant WebGL implementation.
+
+Usage Notes:
+------------
+
+There are various URL options you can pass in.
+
+    run:         Set to 1 to start the tests automatically
+
+                 Example: webgl-conformance-tests.html?run=1
+
+    version:     Set to the version of the harness you wish to run. Tests
+                 at this version or below will be run
+
+                 Example: webgl-conformance-tests.html?version=1.3.2
+
+    minVersion:  Set to the minimum version of each test to include. Only tests
+                 at this version or above will be inlcuded.
+
+                 Example: webgl-conformance-tests.html?minVersion=1.3.2
+
+    fast:        Only run tests not marked with --slow
+
+                 Example: webgl-conformance-tests.html?fast=true
+
+    skip:        Comma separated list of regular expressions of which tests to skip.
+
+                 Example: webgl-conformance-tests.html?skip=glsl,.*destruction\.html
+
+    include:     Comma separated list of regular expressions of which tests to include.
+
+                 Example: webgl-conformance-tests.html?include=glsl,.*destruction\.html
+
+    frames:      The number of iframes to use to run tests in parallel.
+
+                 Example: webgl-conformance-tests.html?frames=8
+
+                 Note the tests are not requried to run with anything other than frames = 1.
