+### Offline/Air-Gapped Environments
+
+By default, common container images are pre-downloaded during the build process:
+
+- K3s system images (pause, coredns, local-path-provisioner, metrics-server)
+- Common base images (nginx, busybox, alpine)
+
+These images are stored in the Docker data volume, so no internet access is required when starting containers.
+
+To disable pre-loading (faster builds if you have good internet):
+
+```bash
+# In .env file
+PRELOAD_IMAGES=false
+```
+
+To add more images to pre-load, edit the Dockerfile and add `docker pull` commands in the pre-load section.

 ## Cleanup

+### 离线/隔离网络环境
+
+默认情况下，在构建过程中会预先下载常用的容器镜像：
+
+- K3s 系统镜像（pause、coredns、local-path-provisioner、metrics-server）
+- 常用基础镜像（nginx、busybox、alpine）
+
+这些镜像存储在 Docker 数据卷中，因此启动容器时无需访问互联网。

+如需禁用预加载（如果网络良好可加快构建速度）：
+
+```bash
+# 在 .env 文件中
+PRELOAD_IMAGES=false

+
+如需添加更多预加载镜像，编辑 Dockerfile 并在预加载部分添加 `docker pull` 命令。
