# nix
> Utilities for the Nix language and store.
> More information: <https://nixos.org>.
> Powerful package manager that makes package management reliable, reproducible, and declarative.
> The `nix` command-line utility is experimental and requires enabling experimental features. For a classic, stable interface, see `tldr nix classic`.
> Some `nix` subcommands such as `build`, `develop`, `flake`, `registry`, `profile`, `search`, `repl`, `store`, `edit`, `why-depends` etc. have their own usage documentation, accessible via `tldr nix3 subcommand`.
> More information: <https://nixos.org/manual/nix>.
