This will install the Nix binaries in <filename>/usr/local</filename>

You can change the former by specifying
<option>--prefix=<replaceable>path</replaceable></option>. The
location of the store can be changed using
<option>--with-store-dir=<replaceable>path</replaceable></option>.
However, you shouldn't change the store location, if at all possible,
since that will make it impossible to use pre-built binaries from the
Nixpkgs channel and other channels. The location of the state can be
changed using
<option>--localstatedir=<replaceable>path</replaceable>.</option></para></listitem>

Note that this in itself doesn't download any packages, it just
downloads the Nix expressions that build them and stores them
somewhere (under <filename>~/.nix-defexpr</filename>, in case you're
curious). Also, it registers the fact that pre-built binaries are
available remotely.</para></listitem>
