# Guardian Shell — Example Configuration
#
# To get started, copy this file and replace /home/user with your actual home:
#   cp config.toml.example config.toml
#   sed -i 's|/home/user|/home/YOUR_USERNAME|g' config.toml
#   sudo target/release/guardian --config config.toml
#
# For preset configs, see configs/ directory:
#   configs/minimal.toml       — Monitor-only, bare minimum
#   configs/recommended.toml   — Production defaults
#   configs/strict.toml        — Maximum security
#   configs/development.toml   — Verbose debugging
