 Java libraries for using OpenAI's GPT-3 api.
 
 Includes the following artifacts:
-- `api` : request/response POJOs for the GPT-3 engine, completion, and search APIs.
+- `api` : request/response POJOs for the GPT-3 APIs.
 - `client` : a basic retrofit client for the GPT-3 endpoints, includes the `api` module

+### Data classes only
+If you want to make your own client, just import the POJOs from the `api` module.
+Your client will need to use snake case to work with the OpenAI API.

+### Retrofit client
+If you're using retrofit, you can import the `client` module and use the [OpenAiApi](client/src/main/java/com/theokanning/openai/OpenAiApi.java).  
+You'll have to add your auth token as a header (see [AuthenticationInterceptor](client/src/main/java/com/theokanning/openai/AuthenticationInterceptor.java))
+and set your converter factory to use snake case and only include non-null fields.
 
-### Using OpenAiService
-If you're looking for the fastest solution, import the `client` and use [OpenAiService](client/src/main/java/com/theokanning/openai/OpenAiService.java).

+### Customizing OpenAiService
+If you need to customize OpenAiService, create your own Retrofit client and pass it in to the constructor.
+For example, do the following to add request logging (after adding the logging gradle dependency):
+```
+ObjectMapper mapper = defaultObjectMapper();
+OkHttpClient client = defaultClient(token, timeout)
+        .newBuilder()
+        .interceptor(HttpLoggingInterceptor())
+        .build();
+Retrofit retrofit = defaultRetrofit(client, mapper);
+
+OpenAiApi api = retrofit.create(OpenAiApi.class);
+OpenAiService service = new OpenAiService(api);
+```
