-## Config
-
-The following parameters are used to configure the plugin:
-
-* **host** - address or IP of the remote machine
-* **port** - port to connect to on the remote machine
-* **user** - user to log in as on the remote machine
-* **passsword** - password to log in as on the remote machine
-* **key** - private SSH key for the remote machine
-* **sleep** - sleep for seconds between host connections
-* **timeout** - timeout for the tcp connection attempt
-* **script** - list of commands to execute
-
-The following secret values can be set to configure the plugin.
-
-* **SSH_HOST** - corresponds to **host**
-* **SSH_PORT** - corresponds to **port**
-* **SSH_USER** - corresponds to **user**
-* **SSH_PASSWORD** - corresponds to **password**
-* **SSH_KEY** - corresponds to **key**
-* **SSH_SLEEP** - corresponds to **sleep**
-* **SSH_TIMEOUT** - corresponds to **timeout**

-In the above example Drone executes the commands on multiple hosts

-list.

-The above example also uses the `sleep` parameter. The sleep parameter
-instructs Drone to sleep for N seconds between host executions.

+## Breaking Changes
+
+As of `v1.5.0`, the command timeout flag has changed to use the `Duration` format. See the following example:
+
+```diff
+pipeline:
+  scp:
+    image: ghcr.io/appleboy/drone-ssh
+    settings:
+      host:

+-     command_timeout: 120
++     command_timeout: 2m
+      script:
+        - echo "Hello World"
 ```
-go build
-go test
+
+## Build or Download a Binary
+
+Pre-compiled binaries are available on the [releases page](https://github.com/appleboy/drone-ssh/releases), supporting the following operating systems:
+
+- Windows amd64/386
+- Linux arm/amd64/386
+- macOS (Darwin) amd64/386
+
+If you have `Go` installed:
+
+```sh
+go install github.com/appleboy/drone-ssh@latest
+```
+
+Or build the binary manually with the following commands:
+
+```sh
+export GOOS=linux
+export GOARCH=amd64
+export CGO_ENABLED=0
+export GO111MODULE=on
+
+go test -cover ./...
+
+go build -v -a -tags netgo -o release/linux/amd64/drone-ssh .
 ```
 
 ## Docker
 
-Build the docker image with the following commands:
+Build the Docker image with the following command:
 
-```
-CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -tags netgo
-docker build -t appleboy/drone-ssh .
-```
-
-Please note incorrectly building the image for the correct x64 linux and with
-GCO disabled will result in an error when running the Docker image:
-
-```
-docker: Error response from daemon: Container command
-'/bin/drone-ssh' not found or does not exist..
+```sh
+make docker
 ```
 
 ## Usage
 
-Execute from the working directory:
+Run from your working directory:
 
 ```sh
 docker run --rm \
   -e PLUGIN_HOST=foo.com \
-  -e PLUGIN_USER=root \
+  -e PLUGIN_USERNAME=root \
   -e PLUGIN_KEY="$(cat ${HOME}/.ssh/id_rsa)" \
   -e PLUGIN_SCRIPT=whoami \
   -v $(pwd):$(pwd) \
   -w $(pwd) \
-  appleboy/drone-ssh
+  ghcr.io/appleboy/drone-ssh
 ```
+
+## Mount Key from File Path
+
+Make sure to enable `trusted` mode in your project settings (for [Drone 0.8 version](https://0-8-0.docs.drone.io/)).
+
+![trusted mode](./images/trust.png)
+
+Mount the private key in the `volumes` section of your `.drone.yml` config:
+
+```diff
+pipeline:
+  ssh:
+    image: ghcr.io/appleboy/drone-ssh
+    host: xxxxx.com
+    username: deploy
++   volumes:
++     - /root/drone_rsa:/root/ssh/drone_rsa
+    key_path: /root/ssh/drone_rsa
+    script:
+      - echo "test ssh"
+```
+
+See details in [this issue comment](https://github.com/appleboy/drone-ssh/issues/51#issuecomment-336732928).
+
+## Configuration
+
+See [DOCS.md](./DOCS.md) for examples and full configuration options.
+
+Configuration options are loaded from multiple sources:
+
+0. Hardcoded drone-ssh defaults. See [main.go CLI Flags](https://github.com/appleboy/drone-ssh/blob/6d9d6acc6aef1f9166118c6ba8bd214d3a582bdb/main.go#L39) for more information.
+1. From a dotenv file at a path specified by the `PLUGIN_ENV_FILE` environment variable.
+2. From your `.drone.yml` Drone configuration.
+
+Later sources override earlier ones. For example, if `PORT` is set in an `.env` file committed in the repository or created by previous test steps, it will override the default set in `main.go`.

+
+`v1.5.0`：将命令超时参数更改为 `Duration` 格式。设置示例如下：
+
+```diff
+pipeline:
+  scp:
+    image: ghcr.io/appleboy/drone-ssh
+    settings:
+      host:
+        - example1.com

+```
+
+## 构建或下载二进制文件
+
+可在[发布页面](https://github.com/appleboy/drone-ssh/releases)下载预编译的二进制文件，支持以下操作系统：
+
+- Windows amd64/386
+- Linux arm/amd64/386
+- macOS (Darwin) amd64/386
+
+如已安装 `Go`，可执行：
+
+```sh
+go install github.com/appleboy/drone-ssh@latest
+```
+
+或使用以下命令手动构建二进制文件：
+
+```sh
+export GOOS=linux
+export GOARCH=amd64
+export CGO_ENABLED=0
+export GO111MODULE=on
+
+go test -cover ./...
+
+go build -v -a -tags netgo -o release/linux/amd64/drone-ssh .
+```
+
+## Docker
+
+可使用以下命令构建 Docker 镜像：
+
+```sh
+make docker
+```
+
+## 使用方法
+
+在工作目录下执行：
+
+```sh
+docker run --rm \
+  -e PLUGIN_HOST=foo.com \
+  -e PLUGIN_USERNAME=root \
+  -e PLUGIN_KEY="$(cat ${HOME}/.ssh/id_rsa)" \
+  -e PLUGIN_SCRIPT=whoami \
+  -v $(pwd):$(pwd) \
+  -w $(pwd) \
+  ghcr.io/appleboy/drone-ssh
+```
+
+## 通过文件路径挂载密钥
+
+请确保已在项目设置中启用 `trusted` 模式（适用于 [Drone 0.8 版本](https://0-8-0.docs.drone.io/)）。
+
+![trusted mode](./images/trust.png)
+
+在 `.drone.yml` 配置文件的 `volumes` 部分挂载私钥：
+
+```diff
+pipeline:
+  ssh:
+    image: ghcr.io/appleboy/drone-ssh
+    host: xxxxx.com
+    username: deploy
++   volumes:
++     - /root/drone_rsa:/root/ssh/drone_rsa
+    key_path: /root/ssh/drone_rsa
+    script:
+      - echo "test ssh"
+```
+
+详情请参考 [此 issue comment](https://github.com/appleboy/drone-ssh/issues/51#issuecomment-336732928)。
+
+## 配置说明
+
+更多示例和完整配置选项请参考 [DOCS.md](./DOCS.md)。
+
+配置选项来源如下：
+
+0. 内置 drone-ssh 默认值。详见 [main.go CLI Flags](https://github.com/appleboy/drone-ssh/blob/6d9d6acc6aef1f9166118c6ba8bd214d3a582bdb/main.go#L39)。
+1. 由 `PLUGIN_ENV_FILE` 环境变量指定的 dotenv 文件。
+2. `.drone.yml` Drone 配置文件。
+
+后面的来源会覆盖前面的设置。例如，`.env` 文件中的 `PORT` 会覆盖 main.go 的默认值。

+pipeline:
+  ssh:
+    image: ghcr.io/appleboy/drone-ssh
+    host: xxxxx.com
+    username: deploy
++   volumes:
++     - /root/drone_rsa:/root/ssh/drone_rsa

+      - echo "test ssh"
+```
+
+詳情請參考 [此 issue comment](https://github.com/appleboy/drone-ssh/issues/51#issuecomment-336732928)。
+
+## 設定說明
+
+更多範例與完整設定選項請參考 [DOCS.md](./DOCS.md)。
+
+設定選項來源如下：
+
+0. 內建 drone-ssh 預設值。詳見 [main.go CLI Flags](https://github.com/appleboy/drone-ssh/blob/6d9d6acc6aef1f9166118c6ba8bd214d3a582bdb/main.go#L39)。
+1. 由 `PLUGIN_ENV_FILE` 環境變數指定的 dotenv 檔案。
+2. `.drone.yml` Drone 設定檔。
+
+後面的來源會覆蓋前面的設定。例如，`.env` 檔案中的 `PORT` 會覆蓋 main.go 的預設值。
