 =========
 
-An open-source communication stack implementation of OPC UA (OPC Unified Architecture) licensed under LGPL + static linking exception.
+open62541 (http://open62541.org) is an open-source implementation of OPC UA (OPC Unified Architecture) licensed under LGPL + static linking exception. The open62541 library can be used to build a dedicated OPC UA server or to integrate OPC UA-based communication into existing applications.
+
+The project is in an early stage but already usable. See below for an simple server implemenation that provides access to a single variable.

-### What is currently working?
-The project is in an early stage. We retain the right to break APIs until a first stable release.
-- Binary serialization of all data types: 100%
-- Node storage and setup of a minimal namespace zero: 100%
-- Standard OPC UA Clients can connect/open a SecureChannel/open a Session: 100%
-- Browsing/reading and writing attributes: 100%
-- Advanced SecureChannel and Session Management: 75%
