+
+<para>The command <command>nix-install-package</command> interactively
+installs a Nix Package file (<filename>*.nixpkg</filename>), which is
+a small file that contains a store path to be installed along with the
+URL of a <link linkend="sec-nix-push"><command>nix-push</command>
+manifest</link>.  The Nix Package file is either
+<replaceable>file</replaceable>, or automatically downloaded from
+<replaceable>url</replaceable> if the <option>--url</option> switch is
+used.</para>
+
+<para><command>nix-install-package</command> is used in <link
+linkend="sec-one-click">one-click installs</link> to download and
+install pre-built binary packages with all necessary dependencies.
+<command>nix-install-package</command> is intended to be associated
+with the MIME type <literal>application/nix-package</literal> in a web
+browser so that it is invoked automatically when you click on
+<filename>*.nixpkg</filename> files.  When invoked, it restarts itself
+in a terminal window (since otherwise it would be invisible when run
+from a browser), asks the user to confirm whether to install the
+package, and if so downloads and installs the package into the user’s
+current profile.</para>
+
+<para>To obtain a window, <command>nix-install-package</command> tries
+to restart itself with <command>xterm</command>,
+<command>konsole</command> and
+<command>gnome-terminal</command>.</para>
