+# Developing I/O connectors for Java
+
+To connect to a data store that isn’t supported by Beam’s existing I/O
+connectors, you must create a custom I/O connector that usually consist of a
+source and a sink. All Beam sources and sinks are composite transforms; 
however,
+the implementation of your custom I/O depends on your use case.  See the [new
+I/O connector overview]({{ site.baseurl 
}}/documentation/io/developing-io-overview/)
+for a general overview of developing a new I/O connector.
+
+This page describes implementation details for developing sources and sinks
+using Java. The Python SDK offers the same functionality, but uses a slightly
+different API. See [Developing I/O connectors for Python]({{ site.baseurl 
}}/documentation/io/developing-io-python/)
+for information specific to the Python SDK.
+
+## Implementation options
+
+**Sources**
+
+For bounded (batch) sources, there are currently two options for creating a 
Beam
+source:
+
+1. Use `ParDo` and `GroupByKey`.
 
 Review comment:
   Done - I worked in a redirect sentence into the intro and removed this whole 
Implementation options section
