 and capabilities, and capnproto-java is a pure Java implementation.
 
 [Read more here.](https://dwrensha.github.io/capnproto-java/index.html)
+
+This repository clone adds an implementation of the RPC framework for Java.
+
+Promise pipelining is provided via java.util.concurrent.CompletableFuture. Unlike the KJ asynchronous model, which completes promises
+only when they are waited upon, a CompletableFuture can complete immediately. This may break E-ordering, as the C++ implementation
+relies on kj::evalLater() to defer method calls and this implementation may have subtle differences.
+
+Most of the C++ RPC test cases have been ported to this implementation, which gives me some comfort that the implementation logic is 
+correct, but more extensive testing is required. 
+
+This implementation does not support generic interfaces. Extending the schema compiler to output code for generic interfaces is an
+exercise I leave to the reader.
