 The suite is provided here in part so that CNF Developers can use the suite to test their CNFs readiness for

+## Container
+
+### Running
+
+To run the tests in the container, use the following command. There are several required arguments:
+
+* `-k` gives a path to the kube config file to be used by the container to authenticate with the cluster.
+* `-t` gives the local directory that contains tnf config files set up for the test.
+* `-o` gives the local directory that the test results will be available in once the container exits.
+* Finally, the specs to be run must be specified.
+
+```shell-script
+./run-container.sh -k ~/.kube/config -t ~/tnf/config -o ~/tnf/output diagnostic generic
+```
+
+### Building
+
+The container can be built using the command below. Use the value of `TNF_VERSION` to set a branch or tag that will be
+installed into the container.
+
+```shell-script
+docker build -t tnf --build-arg TNF_VERSION=1.0.3 .
+```
+
 ## Dependencies
 
 At a minimum, the following dependencies must be installed *prior* to running `make install-tools`.
