+### 配置 Docker 版本的定时更新
+
+Docker 版本现在支持配置定时更新的时间或间隔。您可以通过设置 `UPDATE_CRON` 环境变量来自定义 cron 调度。
+
+#### 1. 设置 `UPDATE_CRON` 环境变量
+
+在运行 Docker 容器时，您可以通过 `-e` 参数设置 `UPDATE_CRON` 环境变量。例如：
+
+```bash
+docker run -d -p 8000:8000 -e UPDATE_CRON="0 6,18 * * *" guovern/tv-requests
+```
+
+上述命令将会在每天的 6:00 和 18:00 进行更新。您可以根据需要修改 `UPDATE_CRON` 的值来设置不同的更新频率。
+
+#### 2. 修改 `config/config.ini` 文件
+
+您还可以在 `config/config.ini` 文件中设置 `update_cron` 参数来指定 cron 调度。例如：
+
+```ini
+update_cron = 0 6,18 * * *
+```
+
+上述配置将会在每天的 6:00 和 18:00 进行更新。您可以根据需要修改 `update_cron` 的值来设置不同的更新频率。

+### Configure Scheduled Updates for Docker Version
+
+The Docker version now supports configuring the update time or interval. You can customize the cron schedule by setting the `UPDATE_CRON` environment variable.
+
+#### 1. Set the `UPDATE_CRON` environment variable
+
+When running the Docker container, you can set the `UPDATE_CRON` environment variable using the `-e` parameter. For example:
+
+```bash
+docker run -d -p 8000:8000 -e UPDATE_CRON="0 6,18 * * *" guovern/tv-requests
+```
+
+The above command will update at 6:00 AM and 6:00 PM every day. You can modify the value of `UPDATE_CRON` as needed to set different update frequencies.
+
+#### 2. Modify the `config/config.ini` file
+
+You can also set the `update_cron` parameter in the `config/config.ini` file to specify the cron schedule. For example:
+
+```ini
+update_cron = 0 6,18 * * *
+```
+
+The above configuration will update at 6:00 AM and 6:00 PM every day. You can modify the value of `update_cron` as needed to set different update frequencies.
