+## 为什么使用 frp ？
+
+通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：
+
+* 客户端服务端通信支持 TCP、KCP 以及 Websocket 等多种协议。
+* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间。
+* 代理组间的负载均衡。
+* 端口复用，多个服务通过同一个服务端端口暴露。
+* 多个原生支持的客户端插件（静态文件查看，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
+* 高度扩展性的服务端插件系统，方便结合自身需求进行功能扩展。
+* 服务端和客户端 UI 页面。
 
 ## 开发状态
 
-frp 仍然处于前期开发阶段，未经充分测试与验证，不推荐用于生产环境。
+frp 目前已被很多公司广泛用于测试、生产环境。
 
 master 分支用于发布稳定版本，dev 分支用于开发，您可以尝试下载最新的 release 版本进行测试。
 
-**目前的交互协议可能随时改变，不保证向后兼容，升级新版本时需要注意公告说明同时升级服务端和客户端。**
+我们正在进行 v2 大版本的开发，将会尝试在各个方面进行重构和升级，且不会与 v1 版本进行兼容，预计会持续一段时间。
 
-## 架构
+现在的 v0 版本将会在合适的时间切换为 v1 版本并且保证兼容性，后续只做 bug 修复和优化，不再进行大的功能性更新。
 
-![architecture](/doc/pic/architecture.png)
+## 文档
 
-## 使用示例
-
-根据对应的操作系统及架构，从 [Release](https://github.com/fatedier/frp/releases) 页面下载最新版本的程序。
-
-将 **frps** 及 **frps.ini** 放到具有公网 IP 的机器上。
-
-将 **frpc** 及 **frpc.ini** 放到处于内网环境的机器上。
-
-### 通过 ssh 访问公司内网机器
-
-1. 修改 frps.ini 文件，这里使用了最简化的配置：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  ```
-
-2. 启动 frps：
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，假设 frps 所在服务器的公网 IP 为 x.x.x.x；
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [ssh]
-  type = tcp
-  local_ip = 127.0.0.1
-  local_port = 22
-  remote_port = 6000
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 通过 ssh 访问内网机器，假设用户名为 test：
-
-  `ssh -oPort=6000 test@x.x.x.x`
-
-### 通过自定义域名访问部署于内网的 web 服务
-
-有时想要让其他人通过域名访问或者测试我们在本地搭建的 web 服务，但是由于本地机器没有公网 IP，无法将域名解析到本地的机器，通过 frp 就可以实现这一功能，以下示例为 http 服务，https 服务配置方法相同， vhost_http_port 替换为 vhost_https_port， type 设置为 https 即可。
-
-1. 修改 frps.ini 文件，设置 http 访问端口为 8080：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  vhost_http_port = 8080
-  ```
-
-2. 启动 frps；
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，假设 frps 所在的服务器的 IP 为 x.x.x.x，local_port 为本地机器上 web 服务对应的端口, 绑定自定义域名 `www.yourdomain.com`:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [web]
-  type = http
-  local_port = 80
-  custom_domains = www.yourdomain.com
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 将 `www.yourdomain.com` 的域名 A 记录解析到 IP `x.x.x.x`，如果服务器已经有对应的域名，也可以将 CNAME 记录解析到服务器原先的域名。
-
-6. 通过浏览器访问 `http://www.yourdomain.com:8080` 即可访问到处于内网机器上的 web 服务。
-
-### 转发 DNS 查询请求
-
-DNS 查询请求通常使用 UDP 协议，frp 支持对内网 UDP 服务的穿透，配置方式和 TCP 基本一致。
-
-1. 修改 frps.ini 文件：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  ```
-
-2. 启动 frps：
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，设置 frps 所在服务器的 IP 为 x.x.x.x，转发到 Google 的 DNS 查询服务器 `8.8.8.8` 的 udp 53 端口：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [dns]
-  type = udp
-  local_ip = 8.8.8.8
-  local_port = 53
-  remote_port = 6000
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 通过 dig 测试 UDP 包转发是否成功，预期会返回 `www.google.com` 域名的解析结果：
-
-  `dig @x.x.x.x -p 6000 www.google.com`
-
-### 转发 Unix域套接字
-
-通过 tcp 端口访问内网的 unix域套接字(例如和 docker daemon 通信)。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，启用 `unix_domain_socket` 插件，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [unix_domain_socket]
-  type = tcp
-  remote_port = 6000
-  plugin = unix_domain_socket
-  plugin_unix_path = /var/run/docker.sock
-  ```
-
-2. 通过 curl 命令查看 docker 版本信息
-
-  `curl http://x.x.x.x:6000/version`
-
-### 对外提供简单的文件访问服务
-
-通过 `static_file` 插件可以对外提供一个简单的基于 HTTP 的文件访问服务。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，启用 `static_file` 插件，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [test_static_file]
-  type = tcp
-  remote_port = 6000
-  plugin = static_file
-  # 要对外暴露的文件目录
-  plugin_local_path = /tmp/file
-  # 访问 url 中会被去除的前缀，保留的内容即为要访问的文件路径
-  plugin_strip_prefix = static
-  plugin_http_user = abc
-  plugin_http_passwd = abc
-  ```
-
-2. 通过浏览器访问 `http://x.x.x.x:6000/static/` 来查看位于 `/tmp/file` 目录下的文件，会要求输入已设置好的用户名和密码。
-
-### 安全地暴露内网服务
-
-对于某些服务来说如果直接暴露于公网上将会存在安全隐患。
-
-使用 **stcp(secret tcp)** 类型的代理可以避免让任何人都能访问到要穿透的服务，但是访问者也需要运行另外一个 frpc。
-
-以下示例将会创建一个只有自己能访问到的 ssh 服务代理。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [secret_ssh]
-  type = stcp
-  # 只有 sk 一致的用户才能访问到此服务
-  sk = abcdefg
-  local_ip = 127.0.0.1
-  local_port = 22
-  ```
-
-2. 在要访问这个服务的机器上启动另外一个 frpc，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [secret_ssh_visitor]
-  type = stcp
-  # stcp 的访问者
-  role = visitor
-  # 要访问的 stcp 代理的名字
-  server_name = secret_ssh
-  sk = abcdefg
-  # 绑定本地端口用于访问 ssh 服务
-  bind_addr = 127.0.0.1
-  bind_port = 6000
-  ```
-
-3. 通过 ssh 访问内网机器，假设用户名为 test：
-
-  `ssh -oPort=6000 test@127.0.0.1`
-
-### 点对点内网穿透
-
-frp 提供了一种新的代理类型 **xtcp** 用于应对在希望传输大量数据且流量不经过服务器的场景。
-
-使用方式同 **stcp** 类似，需要在两边都部署上 frpc 用于建立直接的连接。
-
-目前处于开发的初级阶段，并不能穿透所有类型的 NAT 设备，所以穿透成功率较低。穿透失败时可以尝试 **stcp** 的方式。
-
-1. frps 除正常配置外需要额外配置一个 udp 端口用于支持该类型的客户端:
-
-  ```ini
-  bind_udp_port = 7001
-  ```
-
-2. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [p2p_ssh]
-  type = xtcp
-  # 只有 sk 一致的用户才能访问到此服务
-  sk = abcdefg
-  local_ip = 127.0.0.1
-  local_port = 22
-  ```
-
-3. 在要访问这个服务的机器上启动另外一个 frpc，配置如下:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x

-
-  [p2p_ssh_visitor]
-  type = xtcp

-
-4. 通过 ssh 访问内网机器，假设用户名为 test:
-
-  `ssh -oPort=6000 test@127.0.0.1`
-
-## 功能说明
-
-### 配置文件
-
-由于 frp 目前支持的功能和配置项较多，未在文档中列出的功能可以从完整的示例配置文件中发现。
-
-[frps 完整配置文件](./conf/frps_full.ini)
-
-[frpc 完整配置文件](./conf/frpc_full.ini)
-
-### Dashboard
-
-通过浏览器查看 frp 的状态以及代理统计信息展示。
-
-需要在 frps.ini 中指定 dashboard 服务使用的端口，即可开启此功能：
-
-```ini
-[common]
-dashboard_port = 7500
-# dashboard 用户名密码，默认都为 admin
-dashboard_user = admin
-dashboard_pwd = admin
-```
-
-打开浏览器通过 `http://[server_addr]:7500` 访问 dashboard 界面，用户名密码默认为 `admin`。
-
-![dashboard](/doc/pic/dashboard.png)
-
-### 身份验证
-
-从 v0.10.0 版本开始，所有 proxy 配置全部放在客户端(也就是之前版本的特权模式)，服务端和客户端的 common 配置中的 `token` 参数一致则身份验证通过。
-
-需要注意的是 frpc 所在机器和 frps 所在机器的时间相差不能超过 15 分钟，因为时间戳会被用于加密验证中，防止报文被劫持后被其他人利用。
-
-这个超时时间可以在配置文件中通过 `authentication_timeout` 这个参数来修改，单位为秒，默认值为 900，即 15 分钟。如果修改为 0，则 frps 将不对身份验证报文的时间戳进行超时校验。
-
-### 加密与压缩
-
-这两个功能默认是不开启的，需要在 frpc.ini 中通过配置来为指定的代理启用加密与压缩的功能，压缩算法使用 snappy：
-
-```ini
-# frpc.ini
-[ssh]
-type = tcp
-local_port = 22
-remote_port = 6000
-use_encryption = true
-use_compression = true
-```
-
-如果公司内网防火墙对外网访问进行了流量识别与屏蔽，例如禁止了 ssh 协议等，通过设置 `use_encryption = true`，将 frpc 与 frps 之间的通信内容加密传输，将会有效防止流量被拦截。
-
-如果传输的报文长度较长，通过设置 `use_compression = true` 对传输内容进行压缩，可以有效减小 frpc 与 frps 之间的网络流量，加快流量转发速度，但是会额外消耗一些 cpu 资源。
-
-### 客户端热加载配置文件
-
-当修改了 frpc 中的代理配置，可以通过 `frpc reload` 命令来动态加载配置文件，通常会在 10 秒内完成代理的更新。
-
-启用此功能需要在 frpc 中启用 admin 端口，用于提供 API 服务。配置如下：
-
-```ini
-# frpc.ini
-[common]
-admin_addr = 127.0.0.1
-admin_port = 7400
-```
-
-之后执行重启命令：
-
-`frpc reload -c ./frpc.ini`
-
-等待一段时间后客户端会根据新的配置文件创建、更新、删除代理。
-
-**需要注意的是，[common] 中的参数除了 start 外目前无法被修改。**
-
-### 客户端查看代理状态
-
-frpc 支持通过 `frpc status -c ./frpc.ini` 命令查看代理的状态信息，此功能需要在 frpc 中配置 admin 端口。
-
-### 端口白名单
-
-为了防止端口被滥用，可以手动指定允许哪些端口被使用，在 frps.ini 中通过 `allow_ports` 来指定：
-
-```ini
-# frps.ini
-[common]
-allow_ports = 2000-3000,3001,3003,4000-50000
-```
-
-`allow_ports` 可以配置允许使用的某个指定端口或者是一个范围内的所有端口，以 `,` 分隔，指定的范围以 `-` 分隔。
-
-### 端口复用
-
-目前 frps 中的 `vhost_http_port` 和 `vhost_https_port` 支持配置成和 `bind_port` 为同一个端口，frps 会对连接的协议进行分析，之后进行不同的处理。
-
-例如在某些限制较严格的网络环境中，可以将 `bind_port` 和 `vhost_https_port` 都设置为 443。
-
-后续会尝试允许多个 proxy 绑定同一个远端端口的不同协议。
-
-### TCP 多路复用
-
-从 v0.10.0 版本开始，客户端和服务器端之间的连接支持多路复用，不再需要为每一个用户请求创建一个连接，使连接建立的延迟降低，并且避免了大量文件描述符的占用，使 frp 可以承载更高的并发数。
-
-该功能默认启用，如需关闭，可以在 frps.ini 和 frpc.ini 中配置，该配置项在服务端和客户端必须一致：
-
-```ini
-# frps.ini 和 frpc.ini 中
-[common]
-tcp_mux = false
-```
-
-### 底层通信可选 kcp 协议
-
-从 v0.12.0 版本开始，底层通信协议支持选择 kcp 协议，在弱网环境下传输效率提升明显，但是会有一些额外的流量消耗。
-
-开启 kcp 协议支持：
-
-1. 在 frps.ini 中启用 kcp 协议支持，指定一个 udp 端口用于接收客户端请求：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  # kcp 绑定的是 udp 端口，可以和 bind_port 一样
-  kcp_bind_port = 7000
-  ```
-
-2. 在 frpc.ini 指定需要使用的协议类型，目前只支持 tcp 和 kcp。其他代理配置不需要变更：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  # server_port 指定为 frps 的 kcp_bind_port
-  server_port = 7000
-  protocol = kcp
-  ```
-
-3. 像之前一样使用 frp，需要注意开放相关机器上的 udp 的端口的访问权限。
-
-### 连接池
-
-默认情况下，当用户请求建立连接后，frps 才会请求 frpc 主动与后端服务建立一个连接。当为指定的代理启用连接池后，frp 会预先和后端服务建立起指定数量的连接，每次接收到用户请求后，会从连接池中取出一个连接和用户连接关联起来，避免了等待与后端服务建立连接以及 frpc 和 frps 之间传递控制信息的时间。
-
-这一功能比较适合有大量短连接请求时开启。
-
-1. 首先可以在 frps.ini 中设置每个代理可以创建的连接池上限，避免大量资源占用，客户端设置超过此配置后会被调整到当前值：
-
-  ```ini
-  # frps.ini
-  [common]
-  max_pool_count = 5
-  ```
-
-2. 在 frpc.ini 中为客户端启用连接池，指定预创建连接的数量：
-
-  ```ini
-  # frpc.ini
-  [common]
-  pool_count = 1
-  ```
-
-### 修改 Host Header
-
-通常情况下 frp 不会修改转发的任何数据。但有一些后端服务会根据 http 请求 header 中的 host 字段来展现不同的网站，例如 nginx 的虚拟主机服务，启用 host-header 的修改功能可以动态修改 http 请求中的 host 字段。该功能仅限于 http 类型的代理。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-custom_domains = test.yourdomain.com
-host_header_rewrite = dev.yourdomain.com
-```
-
-原来 http 请求中的 host 字段 `test.yourdomain.com` 转发到后端服务时会被替换为 `dev.yourdomain.com`。
-
-### 获取用户真实 IP
-
-目前只有 **http** 类型的代理支持这一功能，可以通过用户请求的 header 中的 `X-Forwarded-For` 和 `X-Real-IP` 来获取用户真实 IP。
-
-**需要注意的是，目前只在每一个用户连接的第一个 HTTP 请求中添加了这两个 header。**
-
-### 通过密码保护你的 web 服务
-
-由于所有客户端共用一个 frps 的 http 服务端口，任何知道你的域名和 url 的人都能访问到你部署在内网的 web 服务，但是在某些场景下需要确保只有限定的用户才能访问。
-
-frp 支持通过 HTTP Basic Auth 来保护你的 web 服务，使用户需要通过用户名和密码才能访问到你的服务。
-
-该功能目前仅限于 http 类型的代理，需要在 frpc 的代理配置中添加用户名和密码的设置。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-custom_domains = test.yourdomain.com
-http_user = abc
-http_pwd = abc
-```
-
-通过浏览器访问 `http://test.yourdomain.com`，需要输入配置的用户名和密码才能访问。
-
-### 自定义二级域名
-
-在多人同时使用一个 frps 时，通过自定义二级域名的方式来使用会更加方便。
-
-通过在 frps 的配置文件中配置 `subdomain_host`，就可以启用该特性。之后在 frpc 的 http、https 类型的代理中可以不配置 `custom_domains`，而是配置一个 `subdomain` 参数。
-
-只需要将 `*.{subdomain_host}` 解析到 frps 所在服务器。之后用户可以通过 `subdomain` 自行指定自己的 web 服务所需要使用的二级域名，通过 `{subdomain}.{subdomain_host}` 来访问自己的 web 服务。
-
-```ini
-# frps.ini
-[common]
-subdomain_host = frps.com
-```
-
-将泛域名 `*.frps.com` 解析到 frps 所在服务器的 IP 地址。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-subdomain = test
-```
-
-frps 和 fprc 都启动成功后，通过 `test.frps.com` 就可以访问到内网的 web 服务。
-
-需要注意的是如果 frps 配置了 `subdomain_host`，则 `custom_domains` 中不能是属于 `subdomain_host` 的子域名或者泛域名。
-
-同一个 http 或 https 类型的代理中 `custom_domains`  和 `subdomain` 可以同时配置。
-
-### URL 路由
-
-frp 支持根据请求的 URL 路径路由转发到不同的后端服务。
-
-通过配置文件中的 `locations` 字段指定一个或多个 proxy 能够匹配的 URL 前缀(目前仅支持最大前缀匹配，之后会考虑正则匹配)。例如指定 `locations = /news`，则所有 URL 以 `/news` 开头的请求都会被转发到这个服务。
-
-```ini
-# frpc.ini
-[web01]
-type = http
-local_port = 80
-custom_domains = web.yourdomain.com
-locations = /
-
-[web02]
-type = http
-local_port = 81
-custom_domains = web.yourdomain.com
-locations = /news,/about
-```
-
-按照上述的示例配置后，`web.yourdomain.com` 这个域名下所有以 `/news` 以及 `/about` 作为前缀的 URL 请求都会被转发到 web02，其余的请求会被转发到 web01。
-
-### 通过代理连接 frps
-
-在只能通过代理访问外网的环境内，frpc 支持通过 HTTP PROXY 和 frps 进行通信。
-
-可以通过设置 `HTTP_PROXY` 系统环境变量或者通过在 frpc 的配置文件中设置 `http_proxy` 参数来使用此功能。
-
-仅在 `protocol = tcp` 时生效。
-
-```ini
-# frpc.ini
-[common]
-server_addr = x.x.x.x
-server_port = 7000
-http_proxy = http://user:pwd@192.168.1.128:8080
-```
-
-### 范围端口映射
-
-在 frpc 的配置文件中可以指定映射多个端口，目前只支持 tcp 和 udp 的类型。
-
-这一功能通过 `range:` 段落标记来实现，客户端会解析这个标记中的配置，将其拆分成多个 proxy，每一个 proxy 以数字为后缀命名。
-
-例如要映射本地 6000-6005, 6007 这6个端口，主要配置如下：
-
-```ini
-# frpc.ini
-[range:test_tcp]
-type = tcp
-local_ip = 127.0.0.1
-local_port = 6000-6006,6007
-remote_port = 6000-6006,6007
-```
-
-实际连接成功后会创建 6 个 proxy，命名为 `test_tcp_0, test_tcp_1 ... test_tcp_5`。
-
-### 插件
-
-默认情况下，frpc 只会转发请求到本地 tcp 或 udp 端口。
-
-插件模式是为了在客户端提供更加丰富的功能，目前内置的插件有 `unix_domain_socket`、`http_proxy`、`socks5`、`static_file`。具体使用方式请查看[使用示例](#使用示例)。
-
-通过 `plugin` 指定需要使用的插件，插件的配置参数都以 `plugin_` 开头。使用插件后 `local_ip` 和 `local_port` 不再需要配置。
-
-使用 **http_proxy** 插件的示例:
-
-```ini
-# frpc.ini
-[http_proxy]
-type = tcp
-remote_port = 6000
-plugin = http_proxy
-plugin_http_user = abc
-plugin_http_passwd = abc
-```
-
-`plugin_http_user` 和 `plugin_http_passwd` 即为 `http_proxy` 插件可选的配置参数。
-

+### Server Plugin
+
+frp server plugin is aimed to extend frp's ability without modifying the Golang code.
+
+An external server should run in a different process receiving RPC calls from frps.
+Before frps is doing some operations, it will send RPC requests to notify the external RPC server and act according to its response.
+
+### RPC request
+
+RPC requests are based on JSON over HTTP.
+
+When a server plugin accepts an operation request, it can respond with three different responses:
+
+* Reject operation and return a reason.
+* Allow operation and keep original content.
+* Allow operation and return modified content.
+
+### Interface
+
+HTTP path can be configured for each manage plugin in frps. We'll assume for this example that it's `/handler`.
+
+A request to the RPC server will look like:
+
+```
+POST /handler?version=0.1.0&op=Login
+{
+    "version": "0.1.0",
+    "op": "Login",
+    "content": {
+        ... // Operation info
+    }
+}
+
+Request Header:
+X-Frp-Reqid: for tracing
+```
+
+The response can look like any of the following:
+
+* Non-200 HTTP response status code (this will automatically tell frps that the request should fail)
+
+* Reject operation:
+
+```
+{
+    "reject": true,
+    "reject_reason": "invalid user"
+}
+```
+
+* Allow operation and keep original content:
+
+```
+{
+    "reject": false,
+    "unchange": true
+}
+```
+
+* Allow operation and modify content
+
+```
+{
+    "unchange": "false",
+    "content": {
+        ... // Replaced content
+    }
+}
+```
+
+### Operation
+
+Currently `Login`, `NewProxy`, `CloseProxy`, `Ping`, `NewWorkConn` and `NewUserConn` operations are supported.
+
+#### Login
+
+Client login operation
+
+```

+```
+
+#### CloseProxy
+
+A previously created proxy is closed.
+
+Please note that one request will be sent for every proxy that is closed, do **NOT** use this
+if you have too many proxies bound to a single client, as this may exhaust the server's resources.
+
+```

+}
+```
+
+#### NewUserConn
+
+New user connection received from proxy (support `tcp`, `stcp`, `https` and `tcpmux`) .
+
+```
+{
+    "content": {
+        "user": {

+### Server Plugin Configuration
+
+```ini
+# frps.ini
+[common]
+bind_port = 7000
+
+[plugin.user-manager]
+addr = 127.0.0.1:9000
+path = /handler
+ops = Login
+
+[plugin.port-manager]
+addr = 127.0.0.1:9001
+path = /handler
+ops = NewProxy
+```
+
+- addr: the address where the external RPC service listens. Defaults to http. For https, specify the schema: `addr = https://127.0.0.1:9001`.
+- path: http request url path for the POST request.
+- ops: operations plugin needs to handle (e.g. "Login", "NewProxy", ...).
+- tls_verify: When the schema is https, we verify by default. Set this value to false if you want to skip verification.
+
+### Metadata
+
+Metadata will be sent to the server plugin in each RPC request.
+
+There are 2 types of metadata entries - 1 under `[common]` and the other under each proxy configuration.
+Metadata entries under `[common]` will be sent in `Login` under the key `metas`, and in any other RPC request under `user.metas`.
+Metadata entries under each proxy configuration will be sent in `NewProxy` op only, under `metas`.
+
+Metadata entries start with `meta_`. This is an example of metadata entries in `[common]` and under the proxy named `[ssh]`:
+
+```
+# frpc.ini
+[common]
+server_addr = 127.0.0.1
+server_port = 7000
+user = fake
+meta_token = fake
+meta_version = 1.0.0
+
+[ssh]
+type = tcp

+So far, there is no mature Go project that does well in parsing `*.ini` files. 
+
+By comparison, we have selected an open source project: `https://github.com/go-ini/ini`.
+
+This library helped us solve most of the key-value matching, but there are still some problems, such as not supporting parsing `map`.
+
+We add our own logic on the basis of this library. In the current situationwhich, we need to complete the entire `Unmarshal` in two steps:
+
+* Step#1, use `go-ini` to complete the basic parameter matching;
+* Step#2, parse our custom parameters to realize parsing special structure, like `map`, `array`.
+
+Some of the keywords in `tag`(like inline, extends, etc.) may be different from standard libraries such as `json` and `protobuf` in Go. For details, please refer to the library documentation: https://ini.unknwon.io/docs/intro.
