Some examples of types of pull requests that are immediately helpful:

  - Fixing a bug without changing a public API.
  - Fixing or improving documentation.
  - Improvements to Maven configuration.

Guidelines for any code contributions:

  1. Any significant changes should be accompanied by tests. The project already
     has good test coverage, so look at some existing tests if you're unsure

 *  **New Logging Interceptor.** The `logging-interceptor` subproject offers
    simple request and response logging. It may be configured to log headers and
    bodies for debugging. It requires this Maven dependency:

     ```xml
     <dependency>
       <groupId>com.squareup.okhttp</groupId>
       <artifactId>logging-interceptor</artifactId>
       <version>2.6.0</version>
     </dependency>
     ```
