+test-manager is an app for autopkgtest-web which sends kill requests to
+the worker units, detailing the test uuid.
+
+The worker units then kill the test with the matching uuid.
+
+On the running page, admins will have a hyperlink under running jobs which, when clicked,
+will send the kill request.
+
+Before sending the kill request, test_manager checks that the uuid is indeed in running.json
+
+After sending the kill request, the request is picked up by a systemd unit named "test-killer"
+on the cloud worker units.
+
+This unit, through all the cloud worker units, will find which unit the test is running on,
+and kill the test, removing the test request from the queue and making the worker unit move
+on to the next test in the queue.
