 5. 輸入拼音, 就可以看到补全提示
 6. 可以通过修改 rime-ls 的配置项控制补全行为
 
+### 通过容器使用
+
+1. 下载或自行编译 rime-ls 的 docker 镜像
+2. 根据使用需求参考 docker-compose.yaml 以合适的参数运行容器
+3. 其他同上。注意配置客户端时需要使用容器内部的路径
+
+> **Tip**
+> 容器中不包含 Rime 内置输入方案的数据。使用时可以根据需要映射到 `/usr/share/rime-data` 目录，
+> 或者使用 [rime-ice](https://github.com/iDvel/rime-ice/releases/tag/nightly) 
+> 等不依赖 Rime 内置输入方案的方案。
