+<h1>I2PControl - Remote Control Service</h1>
+<p>I2P enables a <a href="http://en.wikipedia.org/wiki/JSON-RPC">JSONRPC2</a> interface via the plugin I2PControl. 
+The aim of the interface is to provide simple way to interface with a running I2P node. A client, itoopie, has been developed in parallel.
+The JSONRPC2 implementation for the client as well as the plugin is provided by the java libraries <a href="http://software.dzhuvinov.com/json-rpc-2.0.html">JSON-RPC 2.0</a>.  
+A list of implementations of JSON-RPC for various languages can be found at <a href="http://json-rpc.org/wiki/implementations">the JSON-RPC wiki</a>.
