 <title>Installing Home Manager</title>
 <para>
  Home Manager can be used in three primary ways:
  <orderedlist>
   <listitem>
    <para>
     Using the standalone <command>home-manager</command> tool. For platforms
     other than NixOS and Darwin, this is the only available choice. It is also
     recommended for people on NixOS or Darwin that want to manage their home
     directory independent of the system as a whole. See
     <xref linkend="sec-install-standalone"/> for instructions on how to
     perform this installation.
    </para>
   </listitem>
   <listitem>
    <para>
     As a module within a NixOS system configuration. This allows the user
     profiles to be built together with the system when running
     <command>nixos-rebuild</command>. See
     <xref linkend="sec-install-nixos-module"/> for a description of this
     setup.
    </para>
   </listitem>
   <listitem>
    <para>
     As a module within a
     <link xlink:href="https://github.com/LnL7/nix-darwin/">nix-darwin</link>
     system configuration. This allows the user profiles to be built together
     with the system when running <command>darwin-rebuild</command>. See

     setup.

  <title>Standalone installation</title>

  <orderedlist>
   <listitem>
    <para>
     Make sure you have a working Nix installation. If you are not using NixOS
     then it may be necessary to run
    </para>
<programlisting>
$ mkdir -m 0755 -p /nix/var/nix/{profiles,gcroots}/per-user/$USER
</programlisting>
    <para>
     since Home Manager uses these directories to manage your profile
     generations. On NixOS these should already be available.
    </para>
    <para>
     Also make sure that your user is able to build and install Nix packages.
     For example, you should be able to successfully run a command like
     <literal>nix-instantiate '&lt;nixpkgs&gt;' -A hello</literal> without
     having to switch to the root user. For a multi-user install of Nix this
     means that your user must be covered by the
     <link xlink:href="https://nixos.org/nix/manual/#conf-allowed-users"><literal>allowed-users</literal></link>
     Nix option. On NixOS you can control this option using the
     <link xlink:href="https://nixos.org/nixos/manual/options.html#opt-nix.allowedUsers"><literal>nix.allowedUsers</literal></link>
     system option.
    </para>
   </listitem>
   <listitem>
    <para>
     Add the Home Manager channel that you wish to follow. This is done by
     running
    </para>
<programlisting>
$ nix-channel --add https://github.com/rycee/home-manager/archive/master.tar.gz home-manager
$ nix-channel --update
</programlisting>
    <para>
     if you are following Nixpkgs master or an unstable channel and
    </para>
<programlisting>
$ nix-channel --add https://github.com/rycee/home-manager/archive/release-18.09.tar.gz home-manager
$ nix-channel --update
</programlisting>
    <para>
     if you follow a Nixpkgs version 18.09 channel.
    </para>
    <para>
     On NixOS you may need to log out and back in for the channel to
     become available. On non-NixOS you may have to add
<programlisting>
export NIX_PATH=$HOME/.nix-defexpr/channels${NIX_PATH:+:}$NIX_PATH
</programlisting>
     to your shell (see
     <link xlink:href="https://github.com/NixOS/nix/issues/2033">nix#2033</link>).
    </para>
   </listitem>
   <listitem>
    <para>
     Run the Home Manager installation command and create the first Home
     Manager generation:
    </para>
<programlisting>
$ nix-shell '&lt;home-manager&gt;' -A install
</programlisting>
    <para>
     Once finished, Home Manager should be active and available in your user
     environment.
    </para>
   </listitem>
   <listitem>
    <para>
     If you do not plan on having Home Manager manage your shell configuration
     then you must source the
    </para>
<programlisting>
$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh
</programlisting>
    <para>
     file in your shell configuration. Unfortunately, we currently only support
     POSIX.2-like shells such as
     <link xlink:href="https://www.gnu.org/software/bash/">Bash</link> or
     <link xlink:href="http://zsh.sourceforge.net/">Z shell</link>.
    </para>
    <para>
     For example, if you use Bash then add
    </para>
<programlisting language="bash">
. &quot;$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh&quot;
</programlisting>
    <para>
     to your <literal>~/.profile</literal> file.
    </para>
   </listitem>
  </orderedlist>

  <para>
   If instead of using channels you want to run Home Manager from a Git
   checkout of the repository then you can use the
   <literal>programs.home-manager.path</literal> option to specify the absolute
   path to the repository.
