+## 单文件发布
 
-服务器上可直接从公开 Release 获取并安装单文件程序：
+构建可直接复制到其他 Linux 服务器的 zipapp：
 
 ```bash
-curl --fail --location https://gitx.roy1994.top/mancitrus/ictlogin/raw/branch/main/install.sh | sh
+python3 scripts/build_release.py
+./dist/ictlogin.pyz --version
+(cd dist && sha256sum -c ictlogin.pyz.sha256)
 ```
 
-安装脚本默认下载 `v0.2.0` Release 中的 `ictlogin.pyz`，验证对应的 SHA-256 后写入 `~/.local/bin/ictlogin`。需要其他版本时设置 Release 标签：
+在包含 `install.sh` 和 `dist/ictlogin.pyz` 的目录中执行：
-
-```bash
-ICTLOGIN_RELEASE_TAG=v0.2.0 ./install.sh
-```
-
-也可以先保存 `install.sh`，再从已有的本地文件或自定义 URL 安装：
 
 ```bash
 ./install.sh
+```
+
+安装脚本默认写入 `~/.local/bin/ictlogin`，会自动校验同目录的 `.sha256` 文件。也可以从指定文件或 URL 安装：
+
+```bash
 ./install.sh --source /path/to/ictlogin.pyz --prefix "$HOME/.local/bin"
 ICTLOGIN_PYZ_URL="https://example.invalid/ictlogin.pyz" ./install.sh
-ICTLOGIN_PYZ_URL="https://example.invalid/ictlogin.pyz" \
-  ICTLOGIN_PYZ_SHA256_URL="https://example.invalid/ictlogin.pyz.sha256" ./install.sh
 ```
 
+当前 Gitea 仓库是私有仓库；在没有仓库访问凭据的服务器上，请先通过 `scp` 复制 `install.sh`、`dist/ictlogin.pyz` 和 `dist/ictlogin.pyz.sha256`，再运行安装脚本。
