# MoShiro 节点一键安装（Windows，Agent 和 Probe 共用同一份）。面板在 /install.ps1?code=… 生成这份脚本，把下面四个值填好：

# irm 'https://panel/install.ps1?code=jt_…' | iex
|

# 镜像：向面板取 CI 签名的发布清单，用内置的发布公钥验签，再按清单里的 digest 拉取。面板还没有签名的清单时，设 $env:MOSHIRO_ALLOW_UNVERIFIED='1' 才会按标签安装。

||
# 做的事：用 Docker Desktop 起一个容器，身份和配置存在命名卷里（重启、换新镜像重建都不用再给参数），节点名字默认取计算机名。
|

# 可选环境变量：MOSHIRO_NAME=节点名字（名字被占用时用）。
