Replace the old command with an updated one in the README.md file, removing the `--use-remote-sudo` option. This should help users to effectively utilize the 'darwin-rebuild' functionality accurately.
Replace `❯` prompt symbol with `$` for clarity and consistency. Add additional command for Darwin. Remove outdated `command-not-found` section. Update nix and ssh command syntax for better readability and usage.
The installation guide in the README file has been modified for clarity. The phrase 'Install system' is updated to 'Install a system' to improve readability and understanding.
