+
+You can configure {Project} to use minimal reporting if you want to limit the data sent to Red{nbsp}Hat.
+You can use minimal reporting to limit the amount of system data sent to the Subscriptions service, which remains active.
+Other Insights services are disabled because they require installed package data, which minimal reports do not include.
+Reports are still processed daily during the midnight synchronization cycle.
+
+Minimal reports also exclude hostnames, IP addresses, and installed packages.
+Therefore, obfuscation and exclusion settings do not apply.
+
+If you switch to *Optional data collection*, {Project} enables the following settings by default:
+
+* Obfuscate host names
+* Obfuscate host ipv4 addresses
+* Exclude installed packages
+
+Review and adjust these settings to control what data {Project} shares.
+
+.Prerequisites
+* Your user account has a role that grants the `edit_settings` permission.
+* Ensure that you delete existing data in Insights Inventory before switching to minimal reporting.
+To remove existing data of a system, navigate to *Inventory* > *Systems* in the {RHCloud}, select the system, and click *Delete*.
+* You have selected an organization and location.       
+
+.Procedure
+. In the {ProjectWebUI}, navigate to *Insights* > *Inventory Upload*.
+. Select the *Minimal data collection* setting from the dropdown menu under *Settings*.
+When you select this option, {Project} also updates the corresponding setting on the *Insights* tab under *Administer* > *Settings*. 
+. Click the *Generate and upload report* button to create a new inventory report and send it to the {RHCloud}.
