+Dotfiles installer (zsh-focused)
+
+Usage:
+  ./install.sh [options]
+
+Options:
+  --theme <name>   Oh My Zsh theme to use (default: clean)
+  --add-nvm        Enable Node Version Manager config
+  --dry-run        Show actions without making changes
+  --help           Show this help and exit
+
+What this does:
+  • Symlinks zsh configuration from this repo
+  • Installs required zsh plugins
+  • Enables syntax highlighting (green/red commands)
+  • Enables fzf history search
+  • Adds ergonomic keybindings
+  • Works on Ubuntu and Fedora
+
+Examples:
+  ./install.sh
+  ./install.sh --theme robbyrussell
+  ./install.sh --add-nvm
+  ./install.sh --theme agnoster --add-nvm --dry-run
