# NetWatch one-line bootstrap installer.

# Clones the repository (or pulls latest changes if already present), then
# runs install.sh. Designed to be safe to invoke via:
#
#   curl -fsSL https://raw.githubusercontent.com/NoCoderRandom/netwatch/main/bootstrap.sh | bash
#
# Environment variables:
#   INSTALL_DIR  Where to clone the repo            (default: $HOME/netwatch)
#   BRANCH       Branch to checkout                 (default: main)
#   REPO         Repository URL                     (default: NoCoderRandom/netwatch)
#
# Anything passed after `bash` is forwarded to install.sh — for example:
#   curl ... | bash -s -- --symlink
