+# Installation (NixOS)
+## Install methods
+### Declarative Nix
+To install with nix, create a `.nix` file like this and import it to your `configuration.nix` :
+```nix
+{ config, pkgs, ... }:
+
+let
+    archbox = pkgs.stdenv.mkDerivation rec {
+        name = "archbox";
+        src = pkgs.fetchFromGitHub {
+            owner = "lemniskett";
+            repo = "archbox";
+            rev = "rev_here";
+            sha256 = "rev_sha256_here";
+        };
+        sourceRoot = ".";
+        installPhase = ''
+            mkdir -p $out
+            cd source
+            export FORCE_INSTALL_CONFIG=1
+            export ETC_DIR=$out/etc
+            export PREFIX=$out
+            export ARCHBOX_USER=your_user_here
+            export MOUNT_RUN=no
+            ${pkgs.bash}/bin/bash install.sh
+        '';
+    };
+in
+{
+    environment.systemPackages = [ archbox ];
+    environment.etc = { 
+        "archbox.conf" = { 
+            source = "${archbox}/etc/archbox.conf";
+        };
+    };
+}
+```
+Replace `your_user_here`, `rev_here`, and `rev_sha256_here`. to get rev and sha256 you can do :
+```sh
+nix-shell -p nix-prefetch-git
+nix-prefetch-git --url https://github.com/lemniskett/archbox.git
+```
+
+Configuration can be done by modifying `installPhase` e.g. :
+```sh
+mkdir -p $out
+cd source
+export FORCE_INSTALL_CONFIG=1
+export ETC_DIR=$out/etc
+export PREFIX=$out
+export ARCHBOX_USER=lemni
+export MOUNT_RUN=no
+export ENV_VAR="TERM=foot"
+export SHARED_FOLDER=( /home /var/www )
+${pkgs.bash}/bin/bash install.sh
+```
