+// Package image provides end-to-end integration tests for runsc. These tests require
+// docker and runsc to be installed on the machine. To set it up, run:
+//
+//     ./runsc/test/install.sh [--runtime <name>]
+//
+// The tests expect the runtime name to be provided in the RUNSC_RUNTIME
+// environment variable (default: runsc-test).
+//
+// Each test calls docker commands to start up a container, and tests that it is
+// behaving properly, with various runsc commands. The container is killed and deleted
+// at the end.
