+```
+
+## 快速开始
+
+### 方法一：使用 Makefile 扩展（推荐）
+
+#### 1. 合并 Makefile
+
+将 `Makefile.offline.mk` 追加到主 Makefile：
+
+```bash
+# Linux/Mac
+cat Makefile.offline.mk >> Makefile
+
+# Windows (PowerShell)
+Get-Content Makefile.offline.mk | Add-Content Makefile
+```
+
+#### 2. 有网环境导出缓存
+
+```bash
+# 导出所有缓存（包括基础镜像、BuildKit 缓存、外部资源）
+make offline-export
+
+# 或者指定输出目录
+make offline-export CACHE_DIR=/path/to/cache
+```
+
+执行完成后，会生成压缩包：`build-cache-YYYYMMDD.tar.gz`
+
+#### 3. 传输到无网环境
+
+```bash
+# 使用 scp 或其他方式传输
+scp build-cache-20250202.tar.gz user@offline-server:/opt/datamate/
+
+# 或者使用 U 盘等物理介质
+```
+
+#### 4. 无网环境构建
+
+```bash
+# 解压缓存
+tar -xzf build-cache-20250202.tar.gz
+
+# 设置环境并构建
+make offline-setup
+make offline-build
+
+# 或者指定版本号
+make offline-build OFFLINE_VERSION=v1.0.0
+```
+
+### 方法二：使用独立脚本
+
+#### 导出缓存
+
+```bash
+cd scripts/offline
+./export-cache.sh /path/to/output
+```
+
+#### 离线构建
+
+```bash
+cd scripts/offline
+./build-offline.sh /path/to/cache [version]
+```
+
+## 详细说明
+
+### 缓存内容
+
+缓存目录结构：
+
+```
+build-cache/
+├── buildkit/                  # BuildKit 缓存
+│   ├── backend-cache/
+│   ├── backend-python-cache/
+│   ├── database-cache/
+│   ├── frontend-cache/
+│   ├── gateway-cache/
+│   ├── runtime-cache/
+│   ├── deer-flow-backend-cache/
+│   ├── deer-flow-frontend-cache/
+│   └── mineru-cache/
+├── images/
+│   └── base-images.tar       # 基础镜像集合
+└── resources/                 # 外部资源
+    ├── models/
+    │   ├── ch_ppocr_mobile_v2.0_cls_infer.tar    # PaddleOCR 模型
+    │   └── zh_core_web_sm-3.8.0-py3-none-any.whl # spaCy 模型
+    ├── DataX/                # DataX 源码
+    └── deer-flow/            # deer-flow 源码
+```
+
+### 单个服务构建
+
+```bash
+# 仅构建 backend
+make backend-offline-build
+
+# 仅构建 runtime
+make runtime-offline-build
+
+# 仅构建 deer-flow-backend
+make deer-flow-backend-offline-build
+```
+
+### 增量更新
+
+如果只有部分服务代码变更，可以只导出该服务的缓存：
+
+```bash
+# 重新导出 backend 缓存
+docker buildx build \
+  --cache-to type=local,dest=./build-cache/buildkit/backend-cache,mode=max \
+  -f scripts/images/backend/Dockerfile \
+  -t datamate-backend:cache .
+
+# 传输并重新构建
+tar -czf build-cache-partial.tar.gz build-cache/buildkit/backend-cache
+# ... 传输到无网环境 ...
+make backend-offline-build
+```
+
+## 故障排查
+
+### 问题 1: 缓存导入失败
+
+```
+ERROR: failed to solve: failed to read cache metadata
+```
+
+**解决**: 缓存目录可能损坏，重新在有网环境导出。
+
+### 问题 2: 基础镜像不存在
+
+```
+ERROR: pull access denied
+```
+
+**解决**: 先执行 `make offline-setup` 加载基础镜像。
+
+### 问题 3: 网络连接错误（无网环境）
+
+```
+ERROR: failed to do request: dial tcp: lookup ...
+```
+
+**解决**: 检查 Dockerfile 中是否还有网络依赖，可能需要修改 Dockerfile 使用本地资源。
+
+### 问题 4: 内存不足
+
+BuildKit 缓存可能占用大量内存，可以设置资源限制：
+
+```bash
+# 创建带资源限制的 buildx 构建器
+docker buildx create --name offline-builder \
+  --driver docker-container \
+  --driver-opt memory=8g \
+  --use
+```
+
+## 限制说明
+
+1. **镜像版本**: 基础镜像版本必须与缓存导出时一致
+2. **Dockerfile 变更**: 如果 Dockerfile 发生较大变更，可能需要重新导出缓存
+3. **资源文件**: mineru 镜像中的模型下载（`mineru-models-download`）仍需要网络，如果需要在完全无网环境使用，需要预先将模型文件挂载到镜像中
+
+## 高级用法
+
+### 自定义缓存位置
+
+```bash
+make offline-export CACHE_DIR=/mnt/nas/build-cache
+make offline-build CACHE_DIR=/mnt/nas/build-cache
+```
+
+### 导出特定平台缓存
+
+```bash
+# 导出 ARM64 平台的缓存
+docker buildx build \
+  --platform linux/arm64 \
+  --cache-to type=local,dest=./build-cache/buildkit/backend-cache,mode=max \
+  -f scripts/images/backend/Dockerfile .
+```
+
+### 使用远程缓存（有网环境）
+
+```bash
+# 导出到 S3/MinIO
+docker buildx build \
+  --cache-to type=s3,region=us-east-1,bucket=mybucket,name=backend-cache \
+  -f scripts/images/backend/Dockerfile .
+
+# 从 S3 导入
+docker buildx build \
+  --cache-from type=s3,region=us-east-1,bucket=mybucket,name=backend-cache \
+  -f scripts/images/backend/Dockerfile .
+```
