# xyz.sh/aapanel — install aaPanel with its official installer.
#
# Official site      : https://www.aapanel.com/new/download.html
# Official installer : https://www.aapanel.com/script/install_7.0_en.sh
#
# This wrapper does not reimplement the panel install. It downloads the
# official installer, prints its URL, SHA256 and first lines, and runs it only
# after confirmation. The installer is interactive, so it needs a terminal
# (run from an SSH session). aaPanel is third-party software with its own
# terms, update channel and data handling; read them before installing.
# Panels open their own web port, install web stacks and change the system
# heavily. Use a fresh server and allow the panel port in your firewall /
# security group yourself.
#
# Usage:
#   curl -fsSL xyz.sh/aapanel | bash
#   curl -fsSL xyz.sh/aapanel | bash -s -- --dry-run
#
# Supported: Debian, Ubuntu, CentOS, Rocky, AlmaLinux (per aapanel.com). Root required.
# No telemetry is added by this wrapper.
