-# eMQTT Get Started
-
-## Overview
-
-eMQTT is a clusterable, massively scalable, fault-tolerant and extensible MQTT V3.1/V3.1.1 broker written in Erlang/OTP. 
-
-eMQTT is aimed to provide a solid-stable broker that could be clusterd to support millions of connections and clients.
-
-## Requires
-
-eMQTT is cross-platform, could run on windows, linux, freebsd and mac os x.
-
-eMQTT requires Erlang R17+ to build from source.
-
-## Featues
-
-### Full MQTT V3.1.1 Support
-
-MQTT V3.1.1 and V3.1 protocol support
-
-QoS0, QoS1, QoS2 Publish and Subscribe
-
-Session Management and Offline Messages
-
-Retained Messages
-
-Passed eclipse paho interoperability tests
-
-### Clusterable, Massively Scalable
-
-Massive Connections Clients Support
-
-Cluster brokers on servers or cloud hosts
-
-Bridge brokers locally or remotelly
-
-## Download, Install
-
-### Download
-
-Dowload binary packages from [http://emqtt.io/downloads](http://emqtt.io/downloads].
-
-Please build from source if no packages for your platform, or contact us.
-
-### Install
-
-Extract tgz package to your installed directory. for example:
-
-```
-tar xvf emqtt-ubuntu64-0.3.0-beta.tgz && cd emqtt  
-```
-
-### Startup
-
-Startup console for debug:
-
-```
-cd emqtt && ./bin/emqtt console
-```
-
-You could see all RECV/SENT MQTT Packages on console.
-
-Start as daemon:
-
-```
-cd emqtt && ./bin/emqtt start
-```
-
-eMQTT occupies 1883 port for MQTT, 8083 for HTTP API.
-
-### Status
-
-```
-cd emqtt && ./bin/emqtt_ctl status
-```
-
-### Stop
-
-```
-cd emqtt && ./bin/emqtt stop
-```
-
-## Configuration
-
-### etc/app.config
-
-```
-{emqtt, [
-    %Authetication. Internal, Anonymous Default.
-    {auth, {anonymous, []}},
-    {access, []},
-    {session, [
-        {expires, 1}, %hours
-        {max_queue, 1000},
-        {store_qos0, false}
-    ]},
-    {retain, [
-        {store_limit, 100000}
-    ]},
-    {listen, [
-        {mqtt, 1883, [
-            {acceptors, 4},
-            {max_conns, 1024}
-        ]},
-        {http, 8083, [
-            {acceptors, 1},
-            {max_conns, 512}
-        ]}
-    ]}
-]}
-```
-
-### etc/vm.args
-
-```
--name emqtt@127.0.0.1
-
--setcookie emqtt
-```
-
-## Cluster
-
-Suppose we cluster two nodes on 'host1', 'host2', Steps:
-
-### configure and start node on host1  
-
-configure 'etc/vm.args':
-
-```
--name emqtt@host1
-```
-
-then start:
-
-```
-./bin/emqtt start
-```
-
-### configure and start node on host2
-
-configure 'etc/vm.args':
-
-```
--name emqtt@host2
-```
-
-```
-./bin/emqtt start
-```
-
-### cluster two nodes
-
-Cluster from 'host2':
-
-```
-./bin/emqtt_ctl cluster emqtt@host1
-```
-
-or cluster from 'host1':
-
-```
-./bin/emqtt_ctl cluster emqtt@host2
-```
-
-then check clustered nodes on any host:
-
-```
-./bin/emqtt_ctl cluster
-```
-
-## HTTP API
-
-eMQTT support HTTP API to publish message from your APP to MQTT client.
-
-Example:
-
-```
-curl -v --basic -u user:passwd -d "qos=1&retain=0&topic=/a/b/c&message=hello from http..." -k http://localhost:8083/mqtt/publish
-```
-
-### URL
-
-```
-HTTP POST http://host:8083/mqtt/publish
-```
-
-### Parameters
-
-Name    |  Description
---------|---------------
-qos     |  QoS(0, 1, 2)
-retain  |  Retain(0, 1)
-topic   |  Topic
-message |  Message

-Authorization of access to Server resources
-
-An implementation may restrict access to Server resources based on information provided by the Client such as User Name, Client Identifier, the hostname/IP address of the Client, or the outcome of authentication mechanisms.

-Identify a MQTT User: Peername, ClientId, Username

-# MQTT Protocol Guide
-
-## Server or Broker
-
-A program or device that acts as an intermediary between Clients which publish Application Messages and Clients which have made Subscriptions. 
-
-A Server Accepts Network Connections from Clients.  
-Accepts Application Messages published by Clients. 
-Processes Subscribe and Unsubscribe requests from Clients.  
-Forwards Application Messages that match Client Subscriptions.
-
-
-Client ----> Broker(Server) ----> Client
-
-Publisher ----> Broker -----> Subscriber
-
-## Subscription and Session
-
-### Subscription
-
-A Subscription comprises a Topic Filter and a maximum QoS. A Subscription is associated with a single Session. A Session can contain more than one Subscription. Each Subscription within a session has a different Topic Filter.
-
-### Session
-
-A stateful interaction between a Client and a Server. Some Sessions last only as long as the Network
-
-Connection, others can span multiple consecutive Network Connections between a Client and a Server.
-
-## Topic Name and Filter
-
-An expression contained in a Subscription, to indicate an interest in one or more topics. A Topic Filter can include wildcard characters.
-
-
-## Packet Identifier

-
-$ cd emqttd
-
-$ make && make dist
-
-$ cd rel/emqttd

-
-### etc/vm.args
-
-```
-
--name emqttd@127.0.0.1
-
--setcookie emqtt
-
-```
-
-When nodes clustered, vm.args should be configured as below:
-
-```
--name emqttd@host1
-```
-
-## Cluster
-
-Suppose we cluster two nodes on 'host1', 'host2', Steps:
-
-on 'host1':
-
-```
-./bin/emqttd start
-```
-
-on 'host2':
-
-```
-./bin/emqttd start
-
-./bin/emqttd_ctl cluster emqttd@host1
-```
-
-Run './bin/emqttd_ctl cluster' on 'host1' or 'host2' to check cluster nodes.
-
-## HTTP API
-
-emqttd support http to publish message.
-
-Example:
-
-```
-curl -v --basic -u user:passwd -d "qos=1&retain=0&topic=a/b/c&message=hello from http..." -k http://localhost:8083/mqtt/publish
-```
-
-### URL
-
-```
-HTTP POST http://host:8083/mqtt/publish
-```
-
-### Parameters
-
-Name    |  Description
---------|---------------
-qos     |  QoS(0, 1, 2)
-retain  |  Retain(0, 1)
-topic   |  Topic
-message |  Message
