-Note connectivity to management network is not needed for most of the testcases.
-But it may be needed for some specific snaps tests.
-
-All the libraries and dependencies needed by all of the Functest tools are
-pre-installed into the Docker images. This allows running Functest on any
-platform.
-
-The automated mechanisms inside the Functest Docker containers will:
-
-  * Prepare the environment according to the System Under Test (SUT)
-  * Perform the appropriate functional tests
-  * Push the test results into the OPNFV test result database (optional)
-
-The OpenStack credentials file must be provided to the container.
-
-These Docker images can be integrated into CI or deployed independently.
-
-Please note that the Functest Docker images have been designed for OPNFV,
-however, it would be possible to adapt them to any OpenStack based VIM +
-controller environment, since most of the test cases are integrated from
-upstream communities.
-
-The functional test cases are described in the Functest User Guide `[2]`_

+All the libraries and dependencies needed by all of the Functest tools are

+platform.
+
+The automated mechanisms inside the Functest Docker containers will:
+
+  * Prepare the environment according to the System Under Test (SUT)
+  * Perform the appropriate functional tests
+  * Push the test results into the OPNFV test result database (optional)
+
+The OpenStack credentials file must be provided to the container.
+
+These Docker images can be integrated into CI or deployed independently.
+
+Please note that the Functest Docker images have been designed for OPNFV,
+however, it would be possible to adapt them to any OpenStack based VIM +
+controller environment, since most of the test cases are integrated from
+upstream communities.
+
+The functional test cases are described in the Functest User `[2]`_
