 ## Why OpenBoot?
 
-**Fresh project, proven demand** — 2 weeks old, already trending on Reddit (100K+ views) and growing fast.

 Brewfiles are manual YAML editing. Nix has a brutal learning curve. Shell scripts break silently. Dotfile repos become unmaintainable after six months.
 
 OpenBoot is the first tool that handles **everything** — packages, dotfiles, shell config, macOS preferences, git identity — in an interactive TUI you can actually navigate. No config files to learn. No YAML to write. Just pick what you need and go.
