+The scripts contained here allow you to build an image of a new or existing connector, and deploy that image into your Kubernetes cluster on your CP4S environment. The are also options for deploying an existing image from a Public registry such as docker hub and for building an image locally so that you may publish it to a registry of your choice. 
 
 The `deploy` script automatically: 
 
 1. Installs the required Python libraries.
 2. [Packages the desired stix-shifter module](https://github.com/opencybersecurityalliance/stix-shifter/blob/master/adapter-guide/develop-stix-adapter.md#Packaging-individual-connectors) into a wheel file.

 4. Signs the image if a certificate is present.
 5. Deploys the image into your cluster.
 
 ## Prerequisites
 
 The following needs to be installed on your local machine: 
 * Python 3
-* Docker
+* Podman (Other Container manangement tool can be used such as Docker)
 * OpenShift CLI (`oc`)
 * Kubernetes CLI (`kubectl`)
 * OpenSSL (`openssl`)
