+Conventions
+-----------
+
+Convention packs allow you to define and apply
+**conventions** to your classes and their members that the driver uses during serialization.
+Conventions specify how data is mapped between your
+{+language+} objects and MongoDB documents without requiring you to decorate
+each class with attributes. 
+
+The {+driver-short+} provides built-in conventions that you can use to
+customize the serialization process. The following table describes some of the
+built-in conventions:
+
+.. list-table::
+   :header-rows: 1
+   :widths: 40 60
+
+   * - Convention
+     - Description
+
+   * - `CamelCaseElementNameConvention <{+new-api-root+}/MongoDB.Bson/MongoDB.Bson.Serialization.Conventions.CamelCaseElementNameConvention.html>`__
+     - Converts element names to camel case during serialization and deserialization.
+
+   * - `EnumRepresentationConvention <{+new-api-root+}/MongoDB.Bson/MongoDB.Bson.Serialization.Conventions.EnumRepresentationConvention.html>`__
+     - Converts enum values to a specified representation during serialization
+       and deserialization.
+
+   * - `IgnoreExtraElementsConvention <{+new-api-root+}/MongoDB.Bson/MongoDB.Bson.Serialization.Conventions.IgnoreExtraElementsConvention.html>`__
+     - Specifies whether to ignore extra elements in a document during deserialization.
+
+   * - `ObjectSerializerAllowedTypesConvention <{+new-api-root+}/MongoDB.Bson/MongoDB.Bson.Serialization.Conventions.ObjectSerializerAllowedTypesConvention.html>`__
+     - Specifies which types are allowed to be serialized using an object
+       serializer.
+
+To view a full list of available conventions, see the `Conventions
+<{+new-api-root+}/MongoDB.Bson/MongoDB.Bson.Serialization.Conventions.html>`__
+class reference in the API Documentation.
+
+You can register a convention by instantiating a ``ConventionPack`` with the
+specified conventions, then passing it to the
+``ConventionRegistry.Register()`` method, as shown in the following example:
+
+.. code-block:: csharp
+
+   var camelCaseConvention = new ConventionPack { new CamelCaseElementNameConvention() };
+   ConventionRegistry.Register("CamelCaseConvention", camelCaseConvention, t => true);
