+"""The config defined in this module is read by mozharness, which is a
+tool used to run many of the tests reporting to TBPL. This file is
+primarily useful for pushing custom test harness configurations to try.
+
+For example you can define a custom mochitest configuration by adding:
+    "mochitest_options": [
+        "--appname=%(binary_path)s", "--utility-path=tests/bin",
+        "--extra-profile-file=tests/bin/plugins", "--symbols-path=%(symbols_path)s",
+        "--certificate-path=tests/certs", "--autorun", "--close-when-done",
+        "--console-level=INFO", "--setpref=webgl.force-enabled=true"
+    ],
+
+Be warned that these values will be picked up by all platforms and changing them
+may result in unexpected behaviour. For example, the above will break B2G
+mochitests.
+
+You must also provide the complete command line to avoid errors. The official
+configuration files containing the default values live in:
+    https://hg.mozilla.org/build/mozharness/configs
