+
+Distributed Object Protocol is a thin layer on top of your data network that helps you communicate server and clients (nodes) using [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). It is also a pattern that makes easy update, mutate or even sync the state of your App using [JSON Merge Patch](https://tools.ietf.org/html/rfc7386).
 
 This repository is the JavaScript implementation of the protocol that runs on node.js and Browsers.

 Distributed Object Protocol is a thin layer on top of your data network that helps you communicate server and clients (nodes) using [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). It is also a pattern that makes easy update, mutate or even sync the state of your App using [JSON Merge Patch](https://tools.ietf.org/html/rfc7386).

-Distributed Object Protocol is a thin layer on top of your data network that helps you communicate server and clients (nodes) using [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). It is also a pattern that makes easy update, mutate or even sync the state of your App using [Patches](https://tools.ietf.org/html/rfc7386).

-Distributed Object Protocol is a thin layer on top of your data network that helps you communicate server and clients (nodes) using [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). It is also a pattern that makes easy update, mutate or even sync the state of your App using [Patches](https://github.com/DistributedObjectProtocol/protocol#Patches).
-
-## Quick example using RPCs with WebSockets
-
-```js
-// Server (node.js)
-const { createNode } = require('dop')
-const WebSocket = require('ws')
-const wss = new WebSocket.Server({ port: 8080 })
-
-const sum = (a, b) => a + b
-const multiply = (a, b) => a * b
-const getCalculator = () => ({ sum, multiply })
-
-wss.on('connection', ws => {
-    const client = createNode()
-    client.open(msg => ws.send(JSON.stringify(msg)), getCalculator)
-    ws.on('message', msg => client.message(JSON.parse(msg)))
-    ws.on('close', client.close)
-})
-```
-
-```js
-// Client (Browser)
-import { createNode } from 'dop'
-const ws = new WebSocket('ws://localhost:8080')
-const server = createNode()
-
-ws.onopen = async () => {
-    const getCalculator = server.open(msg => ws.send(JSON.stringify(msg)))
-    const { sum, multiply } = await getCalculator()
-    const result1 = await sum(5, 5)
-    const result2 = await multiply(5, 5)
-    console.log(result1, result2) // 10, 25
-}
-ws.onmessage = msg => server.message(JSON.parse(msg.data))
-ws.onclose = server.close

 **Distributed Object Protocol** is a thin layer on top of your data network that helps you communicate server and clients (nodes) using [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). It is also a pattern that makes easy update, mutate or even sync the state of your App using [Patches](https://github.com/DistributedObjectProtocol/protocol#Patches).
 
-## RPCs with WebSockets

+## Quick example using RPCs with WebSockets
+
+```js
+// Server
+const { createNode } = require('dop')
+const WebSocket = require('ws')
+const wss = new WebSocket.Server({ port: 8080 })
+
+const sum = (a, b) => a + b
+const multiply = (a, b) => a * b
+const getCalculator = () => ({ sum, multiply })
+
+wss.on('connection', ws => {
+    const client = createNode()
+    client.open(ws.send.bind(ws), getCalculator)
+    ws.on('message', client.message)
+})
+```
+
+```js
+// Client
+const ws = new WebSocket('ws://localhost:8080')
+const server = createNode()
+ws.on('open', async () => {
+    const getCalculator = server.open(ws.send.bind(ws))
+    const { sum, multiply } = await getCalculator()
+    const result1 = await sum(5, 5)
+    const result2 = await multiply(3, 3)
+    console.log(result1, result2) // 10, 9
+})
+ws.on('message', server.message)
+```
