 ## Running integration tests
 
+### Containerized tests
+
 The easiest way to run integration tests is with Docker:
 ```
 $ make integration
 ```
-Alternatively, you can run integration tests directly on your host through make:
-```
-$ sudo make localintegration
-```
-Or you can just run them directly using bats
-```
-$ sudo bats test
-```

 To run a single test bucket:
 ```
 $ make integration TESTFLAGS="runtimeversion.bats"
 ```

+
+#### Runtime selection
+Tests on the host will run with `runc` as the default runtime.
+However you can select other OCI compatible runtimes by setting
+the `RUNTIME` environment variable.
+
+For example one could use the [Clear Containers](https://github.com/01org/cc-oci-runtime/wiki/Installation)
+runtime instead of `runc`:
+
+```
+make localintegration RUNTIME=cc-oci-runtime
