 ## Install
 
 ```bash
-curl -L https://c.jul.sh | sh

 ## How it works
 
 - **Nix + Home Manager** handle packages and environment setup
 - **Symlinks** keep dotfiles live-editable (edit in repo, changes apply immediately)
-- **Local wrappers** like `~/.zshrc` are git-ignored and just source the shared configs (e.g., `~/.zshrc.shared`). This keeps the repo declarative while letting installers and machine-specific tweaks modify the entrypoint freely
