+下载后运行示例（Linux/macOS）：

+## Release Artifact Automation (GitHub Actions)
+
+Built-in workflow: `.github/workflows/release-artifacts.yml`
+
+- Trigger: only when a GitHub Release is `published`
+- No build on normal `push`
+- Outputs: multi-platform binaries (Linux/macOS/Windows) + `sha256sums.txt`
+- Each archive includes:
+- `ds2api` executable (`ds2api.exe` on Windows)
+- `static/admin` (built WebUI assets)
+- `sha3_wasm_bg.7b9ca65ddd.wasm`
+- `config.example.json`, `.env.example`
+- `README.MD`, `README.en.md`, `LICENSE`
+
+Maintainer release flow:
+
+1. Create and publish a GitHub Release (with tag, e.g. `v1.7.0`)
+2. Wait for the `Release Artifacts` workflow to finish
+3. Download the matching archive from Release Assets
+
+Run from downloaded archive (Linux/macOS):
+
+```bash
+tar -xzf ds2api_v1.7.0_linux_amd64.tar.gz
+cd ds2api_v1.7.0_linux_amd64
+cp config.example.json config.json
+./ds2api
+```
