+```js
+var msgpack = require("msgpack-lite");
+
+var codec = msgpack.createCodec();
+codec.addExtPacker(0x3F, MyClass, myClassPacker);
+codec.addExtUnpacker(0x3F, myClassUnpacker);
+msgpack.encode(data, {codec: codec});
+```
+
+The first argument of `addExtPacker` and `addExtUnpacker` should be an integer within the range of 0 and 127 (0x0 and 0x7F). `myClassPacker` is a function that accepts an instance of `MyClass`, and should return a buffer representing that instance. `myClassUnpacker` is the opposite: it accepts a buffer and should return an instance of `MyClass`.
+
+If you pass an array of functions to `addExtPacker` or `addExtUnpacker`, the value to be encoded/decoded will pass through each one in order. This allows you to do things like this:
+
+```js
+codec.addExtPacker(0x00, Date, [Number, msgpack.encode]);
+```
+
+You can also pass the `codec` option to `msgpack.Decoder(options)`, `msgpack.Encoder(options)`, `msgpack.createEncodeStream(options)`, and `msgpack.createDecodeStream(options)`.
+
+If you wish to modify the default built-in codec, you can access it at `msgpack.codec.preset`.
