-Like `packages`, another predefined flake output is `devShells` - which is used to provide a development shell aka. a nix shell or devshell. A devshell is a sandboxed environment containing the packages and other shell environment you specify. nixpkgs provides a function called [`mkShell`][mkShell] that can be used to create devshells.
