 ## 工具安裝
 `make install` 會檢查是否能找到 `clang-format` 與 `clang-tidy`。若缺少任何一項且系統支援 `apt-get`，會嘗試以 `sudo apt-get update` 與 `sudo apt-get install -y` 安裝所需套件（若沒有 `sudo` 則直接呼叫 `apt-get`）。若環境沒有 `apt-get`，指令會提示手動安裝缺少的工具。

+
+## Docker
+提供的 `Dockerfile` 會以 Ubuntu 24.04 建立開發環境，安裝 `clang`、`clang-tidy`、`clang-format` 等工具並執行 `make install` 與 `make`。可以使用以下指令建置並執行容器：
+
+```bash
+docker build -t cpp-template .
+docker run --rm -it cpp-template
+```
+
+如果需要掛載原始碼以便互動開發，可使用：
+
+```bash
+docker run --rm -it -v "$(pwd)":/app -w /app cpp-template bash
+```
+
 ## 下一步
 - 在 `src/` 新增更多檔案與模組。
 - 依專案需求擴充 Makefile 或 utils 腳本。
