+# Open Build Service Appliance QA Suite
+This is a test suite based on perl's [prove](http://perldoc.perl.org/prove.html),
+and [RSpec](http://rspec.info/). We are testing the following:
+
+* The appliance boots and all OBS servers start
+* Sign Up & Log In via the frontend works
+* Building a simple package works
+
+## Running the suite
+This test suite runs [automatically](https://github.com/os-autoinst/os-autoinst-distri-obs)
+against new appliances that got built from
+our [OBS:Server:Unstable](https://build.opensuse.org/project/show/OBS:Server:Unstable)
+on [openQA](https://openqa.opensuse.org/).
+
+
+## QA for package updates
+Additionally our [test instance](https://build-test.opensuse.org/) rebuilds all packages in
+[OBS:Server:Unstable](https://build.opensuse.org/project/show/OBS:Server:Unstable) and
+it's publisher is calling "zypper up" to update itself.
