-## Start
+## Quick Start
 
-Loads all configurations from `/opt/pingap/conf` or file `/opt/pingap/pingap.toml` and run in the background. Log appends to `/opt/pingap/pingap.log`.
+Pingap can be started with either a configuration directory or a single TOML file:
 
 ```bash
+# Using a config directory
 RUST_LOG=INFO pingap -c=/opt/pingap/conf -d --log=/opt/pingap/pingap.log
+
+# Using a single TOML file
+RUST_LOG=INFO pingap -c=/opt/pingap/pingap.toml -d --log=/opt/pingap/pingap.log
 ```
 
-## Graceful restart
+Key flags:
+- `-c`: Path to config directory or TOML file
+- `-d`: Run in daemon/background mode
+- `--log`: Path to log file (logs are appended)
+- `RUST_LOG=INFO`: Set logging level (DEBUG, INFO, WARN, ERROR)
+
+## Graceful Restart
 
-Validate the configurations, send quit signal to pingap, then start a new process to handle all requests.
+Performs a zero-downtime restart of Pingap by following these steps:
+1. Validates the new configuration
+2. Gracefully shuts down the existing process
+3. Starts a new process to handle incoming requests
 
 ```bash
+# Graceful restart command
 RUST_LOG=INFO pingap -c=/opt/pingap/conf -t \
   && pkill -SIGQUIT pingap \
   && RUST_LOG=INFO pingap -c=/opt/pingap/conf -d -u --log=/opt/pingap/pingap.log
 ```
 
-## Auto restart
+Key flags:
+- `-t`: Test/validate configuration before restart
+- `-u`: Upgrade mode (ensures smooth handover from old process)
+- `-d`: Run in daemon mode
+- `SIGQUIT`: Signal for graceful shutdown
 
-Watch the configurations, if one of them changes, graceful restart pingap. `autoreload` means if only the upstream and location configurations are updated, they will take effect about 10s without restarting.
+## Auto Restart
+
+Automatically monitors configuration files and handles changes in two ways:
+- **Full Restart**: When core configurations change, performs a graceful restart
+- **Hot Reload**: When only upstream or location configurations change, updates take effect within ~10 seconds without restart
 
 ```bash
+# Enable auto-restart and hot reload
 RUST_LOG=INFO pingap -c=/opt/pingap/conf \
   -a -d --autoreload --log=/opt/pingap/pingap.log
 ```
 
+Key flags:
+- `-a`: Enable auto-restart on configuration changes
+- `--autoreload`: Enable hot reload for upstream/location changes
+- `-d`: Run in daemon mode
+- `-c`: Path to configuration directory
+
 ## Docker
 
+Run Pingap in a Docker container with auto-restart and admin interface enabled:
+
 ```bash
 docker run -it -d --restart=always \
   -v $PWD/pingap:/opt/pingap \

+Key options:
+- `-it`: Interactive terminal (allows input/output)
+- `-d`: Run container in detached/background mode
+- `--restart=always`: Automatically restart container if it stops
+- `-v $PWD/pingap:/opt/pingap`: Mount local config directory into container
+- `-p 3018:3018`: Expose admin interface port
+- `--autoreload`: Enable hot reload for configuration changes
+- `--admin=user:pass@host:port`: Enable admin interface with credentials
+
+Note: Remember to change the default admin credentials (`pingap:123123`) in production environments.

-## 启用程序
+## 启动服务
 
-从 `/opt/pingap/conf`目录中加载所有配置，并以后台程序的形式运行，日志写入至`/opt/pingap/pingap.log`。
+使用以下命令从指定配置目录启动 Pingap 服务：
 
 ```bash
 RUST_LOG=INFO pingap -c=/opt/pingap/conf -d --log=/opt/pingap/pingap.log
 ```
 
+参数说明：
+- `-c`: 指定配置文件目录
+- `-d`: 以守护进程（后台）模式运行
+- `--log`: 指定日志文件路径
+
 ## 优雅重启
 
-校验配置是否正确后，发送信号给pingap并启动新的程序接收原有的请求。
+执行以下命令可实现零停机重启：
 
 ```bash
 RUST_LOG=INFO pingap -c=/opt/pingap/conf -t \
   && pkill -SIGQUIT pingap \
   && RUST_LOG=INFO pingap -c=/opt/pingap/conf -d -u --log=/opt/pingap/pingap.log
 ```
 
-## 自动重启
+执行步骤：
+1. 验证配置文件正确性 (`-t`)
+2. 向现有进程发送退出信号
+3. 启动新进程接管现有连接 (`-u`)
+
+## 配置热重载
 
-应用启动后，监听相关配置变化，若有变化则无中断式重启程序或热更新加载配置。`autoreload`参数表示如果只是upstream与location的配置变化，则准实时(10秒内)刷新对应配置生效，无需重启。
+启用配置自动重载功能：
 
 ```bash
 RUST_LOG=INFO pingap -c=/opt/pingap/conf \
   -a -d --autoreload --log=/opt/pingap/pingap.log
 ```
 
+特性：
+- `-a`: 启用配置变更监听
+- `--autoreload`: 支持 upstream 和 location 配置的热重载（10秒内生效）
+- 配置变更时自动应用，无需手动重启
