# OdooPilot one-line installer for macOS and Linux.

# Run with:
#   curl -fsSL https://equationx.ai/odoo-pilot/install.sh | bash
#
# What it does:
#   1. Checks for Node.js 20+
#   2. npm install -g pilot-for-odoo
#   3. Launches the interactive setup wizard (pilot-for-odoo-init)
#
# It never modifies your shell config, never asks for sudo unless your Node
# install requires it for global npm packages, and exits cleanly if Node is
# missing with a link to the official download.
