+# Python---Zerto-VRA-Deployment-
+Python based Zerto VRA deployment, user will need to fill out the vras.json file first for each host they would like to deploy a Zerto VRA on. The json file will then be read in by Python to determine the VRA installation options. Within the JSON example they will need to specificy required VRA install options including datastore, network, vra group, as well as static IP information 
+
+# Environment Requirements
