+## VIRL scripts
+
+This directory, and subdirectories, contain files required for automated VIRL testing. These files
+are based on the following assumptions:
+
+ - Files in this directory are installed on the VIRL server host, and scripts in bin/ directory
+ are executable by the user used in the bootstrap.sh script in the root directory of this
+ project
+
+ - the VIRL server has a "server" image, as well as a "vPP" image that is accepting a cloud-init
+ configuration and is ready to receive a VPP upgrade.
+
+ - the VIRL server has an NFS export that can be mounted by VIRL VMs, or there is an NFS server
+ with an export mounted by the VIRL server and mountable by VIRL VMs.
+
+ - the bin/start_testcase script has hardcoded default values both in variable assignments
+ near the beginning of the file, as well as in "parser.add_argument", "default=" options.
+ These may need to be updated.
