+**git archive-all** works similar to ``git archive``, but will also include
 files from submodules into the archive. This is not the only implementation of
 this particular feature, but it is the one that mimics ``git archive`` best.
 It uses the same command line arguments, and in the absense of submodules, it
 will behave identically. Basically, you can use it for all archiving purposes
 and need not think about the technicalities of submodules.

 Installation
 ------------
 
-Just place the ``git-archive-all`` bash script in a location that is in your
-``$PATH``. If you have root privileges, ``/usr/local/bin`` is a reasonable
-choice. Otherwise, you may be able to use ``$HOME/.local/bin`` to the same
-effect, or you can call the script directly without installing it first, albeit
-less conveniently.
+You can run ``make install`` to install **git-archive-all** and its manual
+page. By default, the Makefile will pick ``/usr/local`` as install prefix if
+run as root, and ``$HOME/.local`` otherwise. You can override that choice with
+``make install prefix=/path/to/other/prefix``.
+
+The install script needs ``pod2man`` from the Perl distribution to generate the
+manual page.
+
+
+Testing
+-------
+
+**git-archive-all** comes with a small
+[Bats](https://github.com/bats-core/bats-core) test suite. You can run the test
+suite with ``./test.bats`` if you have installed Bats, e.g. with ``sudo apt
+install bats``.
