TRY IT!
-------
+There are two ways to generate the code needed to work with protocol buffers in Node.js - one approach uses [Protobuf.js](https://github.com/dcodeIO/ProtoBuf.js/) to dynamically generate the code at runtime, the other uses code statically generated using the protocol buffer compiler `protoc`. The examples behave identically, and either server can be used with either client.
+
- Run the server
```sh
$ # from this directory
- $ node ./greeter_server.js &
+ $ node ./dynamic_codegen/greeter_server.js &
+ $ # OR
+ $ node ./static_codegen/greeter_server.js &
```
- Run the client
```sh
$ # from this directory
- $ node ./greeter_client.js
+ $ node ./dynamic_codegen/greeter_client.js
+ $ # OR
+ $ node ./dynamic_codegen/greeter_client.js
```
