+# Install Nix
+
+Install the Nix package manager according to the official documentation on [nixos.org](https://nixos.org/download/).
+
+On Linux, simply run:
+
+```bash
+sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install) --daemon
+```
+
+## Configuration
+
+Add the following to `~/.config/nix/nix.conf` (recommended) or `/etc/nix/nix.conf`:
+
+```ini
+experimental-features = nix-command flakes
+```
+
+- `nix-command` enables the [new `nix` CLI](https://nix.dev/manual/nix/2.29/command-ref/new-cli/nix.html) Nix is transitioning to.
+- `flakes` will be covered later in this guide. Don't worry about them for now.
+
+Reload your session to get access to the `nix` command.
