 ### Overview
 
-Support bundles collect and analyze troubleshooting data from customer environments, helping both users and support teams diagnose problems with application deployments.
+A support bundle is a valuable diagnostic tool that collects and analyzes key troubleshooting data from the customer deployment to enable the end user to self-diagnose and resolve, and when escalating is necessary, it provides the supoprt teams with key necessary information upfront, reducing overall issue resolution time.
+
+The data collected in a support bundle depends on the collectors and redactors defined by the Vendor in the support bundle specification included with the application release. When a support bundle process is generated the process collects defined data from the cluster, redacts sensitive fields, and then perform analysis on the data to provide remediation steps. The output is a compressed tar.gz file that can be subsequently shared during a support escalation.

 Support bundles can also be used for more advanced use cases, such as checking that a command successfully executes in a pod in the cluster, or that an HTTP request returns a succesful response.
 
-Support bundles then use the data collected to provide insights to users on potential problems or suggested troubleshooting steps. The troubleshooting data collected and analyzed by support bundles not only helps users to self-resolve issues with their application deployment, but also helps reduce the amount of time required by support teams to resolve requests by ensuring they have access to all the information they need up front.
+Support bundles also include automatic redactions such as: 
+* database connection strings
+* passwords
+* AWS credentials
+* API token environment variables in JSON
+* URLs that include usernames and passwords
+
+Vendors and end customers can define additional custom redactors to protect sensitive information. Redactors are YAML specifications that define which data to remove when generating a support bundle.
