+## 所需的第三方软件
+- 被监控程序要求JDK6+
+- sky-walking server和webui要求JDK8+
+- Elasticsearch 5.3
+- Zookeeper 3.4.10
+
+## 下载发布版本
+- 前向[发布页面](https://github.com/OpenSkywalking/skywalking/releases)
+
+## 部署Elasticsearch
+- 修改`elasticsearch.yml`文件
+  - 设置 `cluster.name: CollectorDBCluster`。此名称需要和collector配置文件一致。
+  - 设置 `node.name: anyname`, 可以设置为任意名字，如Elasticsearch为集群模式，则每个节点名称需要不同。
+  - 增加如下配置
+
+```
+# ES监听的ip地址
+network.host: 0.0.0.0
+thread_pool.bulk.queue_size: 1000
+```
+
+- 启动Elasticsearch
+
+### 部署collector
+1. 解压安装包`tar -xvf skywalking-collector.tar.gz`，windows用户可以选择zip包
+1. 运行`bin/startup.sh`启动。windows用户为.bat文件。
+
+- `config/application.yml`
+```
+cluster:
+# Zookeeper地址配置
+  zookeeper:
+    hostPort: localhost:2181
+    sessionTimeout: 100000
+# agent_server, agent_stream, ui, collector_inside中配置的IP都是Collector所使用的IP地址
+agent_server:
+  jetty:
+    host: localhost
+    # The port used
+    port: 10800
+    context_path: /
+agent_stream:
+  grpc:
+    host: localhost
+    port: 11800
+  jetty:
+    host: localhost
+    port: 12800
+    context_path: /
+ui:
+  jetty:
+    host: localhost
+    port: 12800
+    context_path: /
+collector_inside:
+  grpc:
+    host: localhost
+    port: 11800
+storage:
+  elasticsearch:
+    cluster_name: CollectorDBCluster
+    cluster_transport_sniffer: true
+    # Elastic Search地址信息
+    cluster_nodes: localhost:9300
+    index_shards_number: 2
+    index_replicas_number: 0
+```
+
+## Collector集群模式启动
+集群模式主要依赖Zookeeper的注册和应用发现能力。所以，你只需要调整 `config/application.yml`中，agent_server, agent_stream, ui, collector_inside这些配置项的ip信息，使用真实的IP地址或者hostname，Collector就会使用集群模式运行。
+其次，将elasticsearch的注释取消，并修改集群的节点地址信息。

docs/cn/Deploy-collector-in-standalone-mode-CN.md

+## 用途说明
+单机模式使用本地H2数据库，不支持集群部署。主要用于：预览、功能测试、演示和低压力系统。
+
+## 所需的第三方软件
+- JDK8+
+
+## 下载发布版本
+- 前向[发布页面](https://github.com/OpenSkywalking/skywalking/releases)
+
+## Quick Start
+Collector单机模拟启动简单，提供和集群模式相同的功能，单机模式下除端口被占用的情况下，直接启动即可。
+
+### 部署collector
+1. 解压安装包`tar -xvf skywalking-collector.tar.gz`，windows用户可以选择zip包
+1. 运行`bin/startup.sh`启动。windows用户为.bat文件。
+
+- `config/application.yml`
+```
+# 单机模式下无需配置集群相关信息
+#cluster:
+#  zookeeper:
+#    hostPort: localhost:2181
+#    sessionTimeout: 100000
+# agent_server, agent_stream, ui, collector_inside中配置的IP都是Collector所使用的IP地址
+agent_server:
+  jetty:
+    host: localhost
+    # The port used
+    port: 10800
+    context_path: /

+

+#  elasticsearch:
+#    cluster_name: CollectorDBCluster
+#    cluster_transport_sniffer: true
+#    Elastic Search地址信息
+#    cluster_nodes: localhost:9300
+#    index_shards_number: 2
+#    index_replicas_number: 0
+```
+
+## 使用Elastic Search代替H2存储
+由于H2数据库性能的局限性，我们在单机模式下，也支持使用ElasticSearch 5.3作为存储。你需要安装对应的ElasticSearch 5.3，并取消
+- 在单机模式下除了支持内置的H2数据库运行，也支持其他的存储（当前已支持的ElasticSearch 5.3以及将会支持的ShardJdbc），安装storage注释，修改配置信息即可。

+## Download skywalking agent release version
+- Go to [release page](https://github.com/OpenSkwaylking/skywalking/releases)
+
+## Deploy skywalking javaagent
+1. Copy the agent package to anywhere you like. The logs, plugins and config are all included in the package.
+2. Add -javaagent:/path/to/skywalking-agent/skywalking-agent.jar to VM argument. 
+
+New agent package looks like this：
+```
++-- skywalking-agent
+    +-- activations
+         apm-toolkit-log4j-1.x-activation.jar
+         apm-toolkit-log4j-2.x-activation.jar
+         apm-toolkit-logback-1.x-activation.jar
+         ...
+    +-- config
+         agent.config  
+    +-- plugins
+         apm-dubbo-plugin.jar
+         apm-feign-default-http-9.x.jar
+         apm-httpClient-4.x-plugin.jar
+         .....
+    skywalking-agent.jar
+```
+
+- Start your application。
+
+# Advanced features
+- All plugins are in `/plugin` folder. The plugin jar is active when it is in there. Remove the plugin jar, it disabled.
+- Besides set config through `/config/agent.config`, you can use System.Env and System.Properties(-D) to set config.
+  - Key of env and properties = `skywalking.` + key in `agent.config` file
+  - Priority: System.Env > System.Properties(-D) > `/config/agent.config`
+- The default logging output folder is `/log`.
+
+# Deploy agent in Tomcat FAQ
+- Tomcat 7
+Change the first line of `tomcat/bin/catalina.sh`.
+```shell
+CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path/to/skywalking-agent/skywalking-agent.jar"; export CATALINA_OPTS
+```
+
+- Tomcat 8
+Change the first line of `tomcat/bin/catalina.sh`.
+```shell
+set "CATALINA_OPTS=... -javaagent:E:\apache-tomcat-8.5.20\skywalking-agent\skywalking-agent.jar -Dconfig=\skywalking\config\dir"
+```
