# A file PowerShell downloads has no "from the internet" mark, so SmartScreen doesn't stop the installer the way
# it stops a browser download. Installs for the current user, without admin. Running it again updates to the
# latest release; your villagers and settings are kept.
# Keep this file ASCII: Windows PowerShell 5.1 may read it in the system code page.
