# provision.sh — set up a new machine from this dotfiles repo
#
# What this does:
#   1. Installs system dependencies (stow, git, neovim, mise, ripgrep)
#   2. Uses stow to symlink each config package into your home directory
#
# What this does NOT do:
#   - Set your git name/email (edit git/.gitconfig yourself)
#   - Run mise install (do that manually after review)
#
# Usage:
#   bash provision.sh          # normal run
#   bash provision.sh --dry-run  # show what would happen, do nothing

# STOW PACKAGES
# ============================================================

# stow creates symlinks in ~ that mirror the package directory structure.
#
# Example: bash/.bashrc → ~/.bashrc
