distro/tests/README.md

+Requirements
+------------
+
+- ansible
+- vagrant
+- libvirt (+vagrant-libvirt) / virtualbox
+
+Usage
+-----
+
+`vagrant up` command is configured to trigger ansible provisioning
+which configures OBS repository, installs the knot package, creates
+a zone and config file, starts the knot.service and attempts to
+resolve the entry from created zone file.
+
+By default, the *knot-dns-latest* repo is used. To test the
+*knot-dns-devel* repo, enable in it `knot-dns-test.yaml`.
+
+Run the following command for every distro (aka directory with
+Vagrantfile):
+
+./test-distro.sh debian9
+
+Caveats
+-------
+
+This tests the latest `knot` package that is available. In certain cases, this
+may result in unexpected behaviour, because it might be testing a different
+package than expected.
