jq
          nox
          silver-searcher
        ];
        pathsToLink = [
          "/share"
          "/bin"
        ];
      };
    };
}
```

`pathsToLink` tells Nixpkgs to only link the paths listed which gets rid of the extra stuff in the profile. `/bin` and `/share` are good defaults for a user environment, getting rid of the clutter. If you are running on Nix on MacOS, you may want to add another path as well, `/Applications`, that makes GUI apps available.

### Getting documentation {#sec-getting-documentation}

After building that new environment, look through `~/.nix-profile` to make sure everything is there that we wanted. Discerning readers will note that some files are missing. Look inside `~/.nix-profile/share/man/man1/` to verify this. There are no man pages for any of the Nix tools! This is because some packages like Nix have multiple outputs for things like documentation (see section 4). Let's make Nix install those as well.

```nix
{
  packageOverrides =
    pkgs: with pkgs; {
      myPackages = pkgs.buildEnv {
        name = "my-packages";
        paths = [
          aspell
          bc
          coreutils
          ffmpeg
          nix
          emscripten
          jq
          nox
          silver-searcher
        ];
        pathsToLink = [
          "/share/man"
          "/share/doc"
          "/bin"
        ];
        extraOutputsToInstall = [
          "man"
          "doc"
        ];
      };
    };
}
```

This provides us with some useful documentation for using our packages.  However, if we actually want those manpages to be detected by man, we need to set up our environment. This can also be managed within Nix expressions.

```nix
{
  packageOverrides = pkgs: {
    myProfile = pkgs.writeText "my-profile" ''
      export PATH=$HOME/.nix-profile/bin:/nix/var/nix/profiles/default/bin:/sbin:/bin:/usr/sbin:/usr/bin
      export MANPATH=$HOME/.nix-profile/share/man:/nix/var/nix/profiles/default/share/man:/usr/share/man
    '';
    myPackages = pkgs.buildEnv {
      name = "my-packages";
      paths = with pkgs; [
        (runCommand "profile" { } ''
          mkdir -p $out/etc/profile.d
          cp ${myProfile} $out/etc/profile.d/my-profile.sh
        '')
        aspell
        bc
        coreutils
        ffmpeg
        man
        nix
        emscripten
        jq
        nox
        silver-searcher
      ];
      pathsToLink = [
        "/share/man"
        "/share/doc"
