# Quick-start installer for the Autonomi `ant` CLI.
#
# Usage:
#   irm https://raw.githubusercontent.com/WithAutonomi/ant-client/main/install.ps1 | iex
#
# Environment variables:
#   ANT_VERSION   - install a specific version (e.g. "0.1.1"). Defaults to latest.
#   INSTALL_DIR   - override install directory (default: %LOCALAPPDATA%\ant\bin).
#
# Verification:
#   Release archives are signed with ML-DSA-65 post-quantum signatures.
#   Download ant-keygen from https://github.com/WithAutonomi/ant-keygen/releases
#   and the public key from resources/release-signing-key.pub in the repository, then:
#     ant-keygen verify --key release-signing-key.pub --input <file> --signature <file>.sig --context ant-release-v1
