+# Note: There are two steps to adding an option to an option page:
+#
+#   1. The option is added to the appropriate section below.
+#      If it's using a default value that may be used elsewhere,
+#      a constant starting with `DEFAULT_` can be added to `const/defaults.py`
+#      and imported here.
+#
+#      The `title` parameter of `Option` is required for options that may be
+#      used in user profiles.
+#      The translated title will be displayed in Profiles option page.
+#
+#   2. If the option is a 'setting' which is edited in one of the option pages,
+#      then the option can be registered in the `__init__()` method of the
+#      matching `OptionPage` declaration with a call to the page's
+#      `register_setting()` method.
+#
+#      Registering a setting allows it to be reset to the default when the user
+#      asks for it on the corresponding option page.
+#
+#      If the setting can be overriden in profiles, the `highlights` parameter
+#      has to be set a list of widget names associated with the option.
+#
+#
+# Please, try to keep options ordered by section and name in their own group.
