#### Prerequisites {#sec-flakes-prerequisites}
To install **nvf** with flakes, you must make sure the following requirements
are met.
1. Nix 2.4 or later must be installed. You may use `nix-shell` to get a later
version of Nix from nixpkgs.
2. Flake-related experimental features must be enabled. Namely, you need
`nix-command` and `flakes`. Some Nix vendors enable those by default, please
consult their documentation if you are not using mainstream Nix.
- When using NixOS, add the following to your `configuration.nix` and rebuild
your system.
```nix
nix.settings.experimental-features = "nix-command flakes";
```
- If you are not using NixOS, add the following to `nix.conf` (located at
`~/.config/nix/` or `/etc/nix/nix.conf`).
```bash
experimental-features = nix-command flakes
```
- You may need to restart the Nix daemon with, for example,
`sudo systemctl restart nix-daemon.service`.
- Alternatively, you can enable flakes on a per-command basis with the
following additional flags to `nix` and `home-manager`:
```sh
# Temporarily enables "nix-command" and "flakes" experimental features.
$ nix --extra-experimental-features "nix-command flakes" <sub-commands>
```
