 # DeepSeek Harness Docker Deploy
 
-Runtime image for [DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) (`dsh`) Web UI.
+Runtime image wrapper for [DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) (`dsh`) Web UI.
 
 The image ships a toolchain only. On every container start, `docker/entrypoint.sh` installs official `@deepseek-ai/dsh@latest` from npm, then starts `dsh web` behind a local port forward (`0.0.0.0:3080` → `127.0.0.1:3081`).
 
-## Quick start
+Prebuilt image (multi-arch `linux/amd64` + `linux/arm64`):
 
-```bash
-docker compose build
-docker compose up -d
-docker logs -f dsh
-# Open the printed URL with ?token= once (30-day cookie). Use host port 3080.

+## Docker Compose (recommended)
+
+```bash
+git clone <this-repo>
+cd DeepSeekHarnessDocker
+docker compose up -d --build   # or image: …/skymirror/dsh:latest without build
+docker compose logs -f dsh
+```
+
+Minimal compose:
+
+```yaml
+services:
+  dsh:
+    image: registry.cn-hangzhou.aliyuncs.com/skymirror/dsh:latest
+    ports:
+      - "3080:3080"
+    volumes:
+      - dsh-data:/home/dsh/.dsh
+      - ./workspace:/workspace
+    environment:
+      - DSH_HOME=/home/dsh/.dsh
+      - HOME=/workspace
+      - DSH_NPM_REGISTRY=https://registry.npmmirror.com
+    restart: unless-stopped
+
+volumes:
+  dsh-data:
+```
+
+## docker run
+
+```bash
+docker run -d --name dsh \
+  --restart unless-stopped \
+  -p 3080:3080 \
+  -v dsh-data:/home/dsh/.dsh \
+  -v "$PWD/workspace":/workspace \
+  -e DSH_HOME=/home/dsh/.dsh \
+  -e HOME=/workspace \
+  -e DSH_NPM_REGISTRY=https://registry.npmmirror.com \
+  registry.cn-hangzhou.aliyuncs.com/skymirror/dsh:latest
+
+docker logs -f dsh
+```
+
+Open the logged `dsh web: http://127.0.0.1:3081/?token=…` URL once with **`:3081` replaced by `:3080`** (30-day cookie). Full guide: [DEPLOY.md](DEPLOY.md) / [中文](README.zh.md).
