+# 环境安装与卸载脚本
+
+这个仓库提供了一组独立的 Shell 脚本，用于安装和卸载常见开发环境工具，适合在 Linux 和 macOS 上快速初始化开发机器。
+
+## 文件说明
+
+- `install.sh`：总安装入口，支持交互式选择或命令行按需安装。
+- `install-docker.sh`：单独安装 Docker。
+- `install-nvm.sh`：单独安装 NVM，并自动安装 Node.js LTS。
+- `install-mambaconda.sh`：单独安装 Mambaconda，默认安装到 `$HOME/mambaconda`。
+- `uninstall.sh`：总卸载入口，支持交互式选择或命令行按需卸载。
+- `uninstall-docker.sh`：单独卸载 Docker，默认保留 Docker 数据。
+- `uninstall-nvm.sh`：单独卸载 NVM，并清理脚本追加的 Shell 初始化配置。
+- `uninstall-mambaconda.sh`：单独卸载 Mambaconda，并清理脚本追加的 Shell 初始化配置。
+
+## 支持平台
+
+- Linux
+- macOS
+
+## 安装用法
+
+总入口安装：
+
+```bash
+bash install.sh
+```
+
+常见用法：
+
+```bash
+bash install.sh all
+bash install.sh docker
+bash install.sh nvm mambaconda
+```
+
+也可以直接执行单独脚本：
+
+```bash
+bash install-docker.sh
+bash install-nvm.sh
+bash install-mambaconda.sh
+```
+
+`install.sh` 支持以下模式：
+
+- 不带参数：交互式选择安装项
+- `all`：安装全部工具
+- `docker` / `nvm` / `mambaconda`：安装指定工具
+- 多个参数组合：安装多个指定工具
+
+## 卸载用法
+
+总入口卸载：
+
+```bash
+bash uninstall.sh
+```
+
+常见用法：
+
+```bash
+bash uninstall.sh all
+bash uninstall.sh docker
+bash uninstall.sh nvm mambaconda
+```
+
+也可以直接执行单独脚本：
+
+```bash
+bash uninstall-docker.sh
+bash uninstall-nvm.sh
+bash uninstall-mambaconda.sh
+```
+
+`uninstall.sh` 支持以下模式：
+
+- 不带参数：交互式选择卸载项
+- `all`：卸载全部工具
+- `docker` / `nvm` / `mambaconda`：卸载指定工具
+- 多个参数组合：卸载多个指定工具
+
+## 默认行为说明
+
+- `install-nvm.sh` 会配置 Node.js 国内镜像和 npm 国内源。
+- `install-mambaconda.sh` 会写入 `~/.condarc`，并使用国内镜像源。
+- `install-mambaconda.sh` 默认会安装 Python 3.10。
+- `uninstall-docker.sh` 默认不会删除 Docker 数据目录。
+
+如果需要在卸载 Docker 时同时删除数据，可使用：
+
+```bash
+REMOVE_DOCKER_DATA=1 bash uninstall-docker.sh
+```
+
+## 安装后验证
+
+```bash
+docker --version
+docker compose version
+nvm --version && node --version && npm --version
+conda --version && python --version
+```
+
+## 输出风格
+
+现在所有入口脚本和子脚本都会使用统一的输出格式：
+
+- `INFO`：普通步骤提示
+- `WARN`：非阻断警告
+- `ERROR`：错误并退出
+- `DONE`：当前脚本执行完成
+
+同时会显示阶段标题，便于在安装或卸载过程中快速定位当前步骤。
