+# Docker usage
+
+Build:
+
+```bash
+docker build -t deepseek-2api .
+```
+
+Run on default port 7860:
+
+```bash
+docker run -d --name deepseek-2api -p 7860:7860 \
+  -e DS_TOKEN=your_token \
+  -e API_KEY=your_api_key \
+  deepseek-2api
+```
+
+Environment variables:
+
+- `DS_TOKEN`: DeepSeek token. Takes precedence.
+- `DS_EMAIL` / `DS_PASSWORD`: DeepSeek email/password fallback.
+- `PORT`: service port. Defaults to `7860`.
+- `API_KEY`: optional service API key. Leave empty to disable auth.
+- `USE_WASM_POW`: optional. Set to `false` to skip WASM PoW and use BigInt directly.
+
+If you have `sha3_wasm_bg.wasm`, place it in the project root before building. The Docker image will copy it. If it is absent, the service automatically falls back to the BigInt implementation.
