+### Configuration file template
+
+Configuration file tempalte can be rendered using os environments. Template uses Go's standard format.
+
+```ini
+# frpc.ini
+[common]
+server_addr = {{ .Envs.FRP_SERVER_ADDR }}
+server_port = 7000
+
+[ssh]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 22
+remote_port = {{ .Envs.FRP_SSH_REMOTE_PORT }}
+```
+
+Start frpc program:
+
+```
+export FRP_SERVER_ADDR="x.x.x.x"
+export FRP_SSH_REMOTE_PORT="6000"
+./frpc -c ./frpc.ini
+```
+
+frpc will auto render configuration file template using os environments.
+All environments has prefix `.Envs`.

+### 配置文件模版渲染
+
+配置文件支持使用系统环境变量进行模版渲染，模版格式采用 Go 的标准格式。
+
+示例配置如下:
+
+```ini
+# frpc.ini
+[common]
+server_addr = {{ .Envs.FRP_SERVER_ADDR }}
+server_port = 7000
+
+[ssh]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 22
+remote_port = {{ .Envs.FRP_SSH_REMOTE_PORT }}
+```
+
+启动 frpc 程序:
+
+```
+export FRP_SERVER_ADDR="x.x.x.x"
+export FRP_SSH_REMOTE_PORT="6000"
+./frpc -c ./frpc.ini
+```
+
+frpc 会自动使用环境变量渲染配置文件模版，所有环境变量需要以 `.Envs` 为前缀。
