+Some of the Java FDK's features include:
 
-Alternatively for Linux/Unix/MacOS:
+- Parsing input and writing output
+- Flexible data binding to Java objects
+- Function testing using JUNit rules
+- And more!

+## Using the Java FDK
 
-## Fn Java FDK Development Information
-### Contributing
-Please see [CONTRIBUTING.md](CONTRIBUTING.md).
-
-### Fn Java FDK FAQ
-Some common questions are answered in [our FAQ](docs/FAQ.md).
-
-### Fn Java FDK Tutorials and Examples
-
-#### Examples
-Check out Java FDK examples in the [`examples`](examples) directory for
-functions demonstrating different Fn Java FDK features.
+For detailed instructions on using the Java FDK to build and deploy Java functions to Fn, please see the official Java FDK developer guide in our docs repo here: https://github.com/fnproject/docs/blob/master/fdks/fdk-java/README.md.
 
-#### Configuring your Function
-Want to set up function object state before the function is invoked using external configuration variables?  Have a look at the [Function
-Configuration](docs/FunctionConfiguration.md) tutorial.

-#### Handling HTTP Requests
-Want to access HTTP details such as request or response headers or the HTTP status? Check out [Accessing HTTP Information from Functions](docs/HTTPGatewayFunctions.md).
-
-#### Input and Output Bindings
-You have the option of taking more control of how serialization and
-deserialization is performed by defining your own bindings.
-
-See the [Data Binding](docs/DataBinding.md) tutorial for other out-of-the-box
-options and the [Extending Data Binding](docs/ExtendingDataBinding.md) tutorial
-for how to define and use your own bindings.
-
-#### Asynchronous Workflows
-Suppose you want to call out to some other function from yours - perhaps
-a function written in a different language, or even one maintained by
-a different team. Maybe you then want to do some processing on the result. Or
-even have your function interact asynchronously with a completely different
-system. Perhaps you also need to maintain some state for the duration of your
-function, but you don't want to pay for execution time while you're waiting for
-someone else to do their work.
+Please see [CONTRIBUTING.md](CONTRIBUTING.md).
 
-If this sounds like you, then have a look at the [Fn Flow
-Quickstart](docs/FnFlowsUserGuide.md).
