-Yjs is a framework for optimistic concurrency control and automatic conflict resolution on arbitrary data types. The framework implements a new OT-like concurrency algorithm and provides similar functionality as [ShareJs] and [OpenCoweb]. Yjs was designed to take away the pain from concurrently editing complex data types like Text, Json, and XML. You can find some applications for this framework [here](https://dadamonad.github.io/yjs/examples/).
+Yjs is a framework for optimistic concurrency control and automatic conflict resolution on arbitrary data types. The framework implements a new OT-like concurrency algorithm and provides similar functionality as [ShareJs] and [OpenCoweb].

+You can create your own shared data types easily. Therefore, you can take matters into your own hand by defining the meaning of the shared types and ensure that it is valid, while Yjs ensures data consistency (everyone will eventually end up with the same data).

 Unlike other frameworks, Yjs supports P2P message propagation and is not bound to a specific communication protocol. Therefore, Yjs is extremely scalable and can be used in a wide range of application scenarios.
 
-We support several communication protocols as so called *Connectors*. You can create your own connector too - as it is described [here](https://dadamonad.github.io/yjs/connector/Howto-create-your-own-Connector.html). Currently, we support the following communication protocols:
-* [XMPP-Connector](http://xmpp.org) - Propagates updates in a XMPP multi-user-chat room
-* [WebRTC-Connector](http://peerjs.com) - Propagate updates directly with WebRTC
-* [IWC-Connector](http://dbis.rwth-aachen.de/cms/projects/the-xmpp-experience#interwidget-communication) - Inter-widget Communication

-## Status
-Yjs is still in an early development phase. Don't expect that everything is working fine.
-But I would become really motivated if you gave me some feedback :) ([github](https://github.com/rwth-acis/yjs/issues)).
+# Y()
+In order to create an instance of Y, you need to have a connection object (instance of a Connector). Then, you can create a shared data type like this:
+```
+var y = new Y(connector);
+```
 
-### Current Issues
-* The History Buffer should be able to store operations in a database
-* Documentation
-* Reimplement support for XML as a data type
-* Custom data types
 
+# Y.Object
+Yjs includes only one type by default - the Y.Object type. It mimics the behaviour of a JSON Object. You can create, update, and remove properies on the Y.Object type. Furthermore, you can observe changes on this type as you can observe changes on Javascript Objects with [Object.observe](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/observe) - an ECMAScript 7 proposal which is likely to become accepted by the committee. Until then, we have our own implementation.
+
+
+##### Reference
+* Create
+```
+var y = new Y.Object();
+```
+* Create with existing Object
+```
+var y = new Y.Object({number: 73});
+```
+* Every instance of Y is an Y.Object
+```
+var y = new Y(connector);
+```
+* .val()
+  * Retrieve all properties of this type as a JSON Object
+* .val(name)
+  * Retrieve the value of a property
+* .val(name, value)
+  * Set/update a property. Returns `this` Y.Object
+* .delete(name)
+  * Delete a property
+* .observe(observer)
+  * The `observer` is called whenever something on this object changes. Throws *add*, *update*, and *delete* events
+* .unobserve(f)
+  * Delete an observer
+
+# A note on intention preservation
+When users create/update/delete the same property concurrently, only one change will prevail. Changes on different properties do not conflict with each other.
+
+# A note on time complexities
+* .val()
+  * O(|properties|)
+* .val(name)
+  * O(1)
+* .val(name, value)
+  * O(1)
+* .delete(name)
+  * O(1)
+* Apply a delete operation from another user
+  * O(1)
+* Apply an update operation from another user (set/update a property)
+  * Yjs does not transform against operations that do not conflict with each other.
+  * An operation conflicts with another operation if it changes the same property.
+  * Overall worst case complexety: O(|conflicts|!)
+
+# Status
+Yjs is a work in progress. Different versions of the *y-* repositories may not work together. Just drop me a line if you run into troubles.

 ## Contribution
 I created this framework during my bachelor thesis at the chair of computer science 5 [(i5)](http://dbis.rwth-aachen.de/cms), RWTH University. Since December 2014 I'm working on Yjs as a part of my student worker job at the i5.
