+# Overview
+This repository provides various Protocol Buffer extensions for the Go
+language (golang), namely support for record length-delimited message
+streaming.
+
+| Java | Go |
+| ------------------------------ | --------------------- |
+| MessageLite#parseDelimitedFrom | pbutil.ReadDelimited |
+| MessageLite#writeDelimitedTo | pbutil.WriteDelimited |
+
+Because [Code Review 9102043](https://codereview.appspot.com/9102043/) is
+destined to never be merged into mainline (i.e., never be promoted to formal
+[goprotobuf features](https://github.com/golang/protobuf)), this repository
+will live here in the wild.
+
+# Documentation
+We have [generated Go Doc documentation](http://godoc.org/github.com/matttproud/golang_protobuf_extensions/pbutil) here.
+
+# Testing
