 # ![Yjs](http://y-js.org/images/yjs.png)
-Yjs is a framework for optimistic concurrency control and automatic conflict resolution on shared data.
+Yjs is a framework for offline-first p2p shared editing on structured data like text, richtext, json, or XML.
-The framework provides similar functionality as [ShareJs] and [OpenCoweb], but supports peer-to-peer
+It is fairly easy to get started, as Yjs hides most of the complexity of concurrent editing.
-communication protocols by default. Yjs was designed to handle concurrent actions on arbitrary data
+For additional information, demos, and tutorials visit [y-js.org](http://y-js.org/).
 like Text, Json, and XML. We also provide support for storing and manipulating your shared data offline.
 For more information and demo applications visit our [homepage](http://y-js.org/).
-You can create you own shared types easily.
+### Extensions
-Therefore, you can design the structure of your custom type,
+Yjs only knows how to resolve conflicts on shared data. You have to choose a ..
-and ensure data validity, while Yjs ensures data consistency (everyone will eventually end up with the same data).
+* *Connector* - a communication protocol that propagates changes to the clients 
-We already provide abstract data types for
+* *Database* - a database to store your changes
 * one or more *Types* - that represent the shared data
 Connectors, Databases, and Types are available as modules that extend Yjs. Here is a list of the modules we know of:
 ##### Connectors
 |Name            | Description               |
 |----------------|-----------------------------------|
 |[webrtc](https://github.com/y-js/y-webrtc) | Propagate updates Browser2Browser via WebRTC|
 |[websockets](https://github.com/y-js/y-websockets-client) | Set up [a central server](https://github.com/y-js/y-websockets-client), and connect to it via websockets |
 |[xmpp](https://github.com/y-js/y-xmpp) | Propagate updates in a XMPP multi-user-chat room ([XEP-0045](http://xmpp.org/extensions/xep-0045.html))|
 |[test](https://github.com/y-js/y-test) | A Connector for testing purposes. It is designed to simulate delays that happen in worst case scenarios|
 ##### Database adapters
 |Name            | Description               |
 |----------------|-----------------------------------|
 |[memory](https://github.com/y-js/y-memory) | In-memory storage. |
 |[indexeddb](https://github.com/y-js/y-indexeddb) | Offline storage for the browser |
 |[leveldb](https://github.com/y-js/y-leveldb) | Persistent storage for node apps |
 ##### Types
 | Name     | Description       |
 |----------|-------------------|
 |[map](https://github.com/y-js/y-map) | A shared Map implementation. Maps from text to any stringify-able object |
 |[array](https://github.com/y-js/y-array) | A shared Array implementation |
 |[xml](https://github.com/y-js/y-xml) | An implementation of the DOM. You can create a two way binding to Browser DOM objects |
-|[text](https://github.com/y-js/y-text) | Collaborate on text. Supports two way binding to textareas, input elements, or HTML elements (e.g. <*h1*>, or <*p*>). Also supports the [Ace Editor](https://ace.c9.io) |
+|[text](https://github.com/y-js/y-text) | Collaborate on text. Supports two way binding to the [Ace Editor](https://ace.c9.io), textareas, input elements, and HTML elements (e.g. <*h1*>, or <*p*>) |
 |[richtext](https://github.com/y-js/y-richtext) | Collaborate on rich text. Supports two way binding to the [Quill Rich Text Editor](http://quilljs.com/)|
-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.
+## Use it! 
-
+Install Yjs, and its modules with [bower](http://bower.io/), or [npm](https://www.npmjs.org/package/yjs).
 We support several communication protocols as so called *Connectors*.
 You can create your own connector too - read [this wiki page](https://github.com/y-js/yjs/wiki/Custom-Connectors).
 Currently, we support the following communication protocols:
 |Name            | Description               |
 |----------------|-----------------------------------|
 |[xmpp](https://github.com/y-js/y-xmpp) | Propagate updates in a XMPP multi-user-chat room ([XEP-0045](http://xmpp.org/extensions/xep-0045.html))|
 |[webrtc](https://github.com/y-js/y-webrtc) | Propagate updates Browser2Browser via WebRTC|
 |[websockets](https://github.com/y-js/y-websockets-client) | Exchange updates efficiently in the classical client-server model |
 |[test](https://github.com/y-js/y-test) | A Connector for testing purposes. It is designed to simulate delays that happen in worst case scenarios|
 You are not limited to use a specific database to store the shared data. We provide the following database adapters:
 |Name            | Description               |
 |----------------|-----------------------------------|
 |[memory](https://github.com/y-js/y-memory) | In-memory storage. |
 |[indexeddb](https://github.com/y-js/y-indexeddb) | Offline storage for the browser |
 The advantages over similar frameworks are support for
 * .. P2P message propagation and arbitrary communication protocols
 * .. share any type of data. The types provide a convenient interface
 * .. offline support: Changes are stored persistently and only relevant changes are propagated on rejoin
 * .. Intention Preservation: When working on Text, the intention of your changes are preserved. This is particularily important when working offline. Every type has a notion on how we define Intention Preservation on it.
 ## Use it!
 Install yjs and its modules with [bower](http://bower.io/), or with [npm](https://www.npmjs.org/package/yjs).
 ### Bower
 ```
-bower install yjs --save
+bower install --save yjs y-array % add all y-* modules you want to use
 ```
-Then you include the libraries directly from the installation folder.
+You only need to include the `y.js` file. Yjs is able to automatically require missing modules.  
 ```
 <script src="./bower_components/yjs/y.js"></script>
 ```
 ### Npm
 ```
-npm install yjs --save
+npm install --save yjs % add all y-* modules you want to use
 ```
-And use it like this with *npm*:
+If you don't include via script tag, you have to explicitly include all modules! (Same goes for other module systems)
 ```
-Y = require("yjs");
+var Y = require('yjs')
 require('y-array')(Y) // add the y-array type to Yjs
 require('y-websockets-client')(Y)
 require('y-memory')(Y)
 require('y-array')(Y)
 require('y-map')(Y)
 require('y-text')(Y)
 // ..
 // do the same for all modules you want to use
 ```
 ### ES6 Syntax
 ```
 import Y from 'yjs'
 import yArray from 'y-array'
 import yWebsocketsClient from 'y-webrtc'
 import yMemory from 'y-memory'
 import yArray from 'y-array'
 import yMap from 'y-map'
 import yText from 'y-text'
 // ..
 Y.extend(yArray, yWebsocketsClient, yMemory, yArray, yMap, yText /*, .. */)
 ```
 # Text editing example
 Install dependencies
 ```
-Y({
+bower i yjs y-memory y-webrtc y-array y-text
  db: {
    name: 'memory' // store in memory.
    // name: 'indexeddb'
  },
  connector: {
    name: 'websockets-client', // choose the websockets connector

  },
  sourceDir: '/bower_components', // location of the y-* modules
  share: {
    textarea: 'Text' // y.share.textarea is of type Y.Text
  }
  // types: ['Richtext', 'Array'] // optional list of types you want to import
 }).then(function (y) {
  // bind the textarea to a shared text element
  y.share.textarea.bind(document.getElementById('textfield'))
 }
 ```
