sh <(curl -L https://nixos.org/nix/install) --daemon

:::{note} For security you may want to verify the installation script using GPG signatures. :::

macOS

Install Nix via the recommended multi-user installation:

sh <(curl -L https://nixos.org/nix/install)

:::{note} For security you may want to verify the installation script using GPG signatures. :::

Windows (WSL2)

Install Nix via the recommended single-user installation:

sh <(curl -L https://nixos.org/nix/install) --no-daemon

:::{note} For security you may want to verify the installation script using GPG signatures. :::

Docker

Start a Docker shell with Nix:

$ docker run -it nixos/nix

Or start a Docker shell with Nix exposing a workdir directory:

$ mkdir workdir
$ docker run -it -v $(pwd)/workdir:/workdir nixos/nix

The workdir example from above can be also used to start hacking on nixpkgs:

$ git clone git@github.com:NixOS/nixpkgs
$ docker run -it -v $(pwd)/nixpkgs:/nixpkgs nixos/nix
docker> nix-build -I nixpkgs=/nixpkgs -A hello
docker> find ./result # this symlink points to the build package

Verify installation

Check that the installation by opening a new terminal and typing:

$ nix --version
nix (Nix) 2.11.0
