 ### Telemetry
 
-By default, PowerShell collects the OS description and the version of PowerShell (equivalent to `$PSVersionTable.OS` and `$PSVersionTable.GitCommitId`) using [Application Insights](https://azure.microsoft.com/services/application-insights/).
-To opt-out of sending telemetry, create an environment variable called `POWERSHELL_TELEMETRY_OPTOUT` set to a value of `1` before starting PowerShell from the installed location.
-The telemetry we collect falls under the [Microsoft Privacy Statement](https://privacy.microsoft.com/privacystatement/).
+Please visit our [about_Telemetry](https://docs.microsoft.com/powershell/module/microsoft.powershell.core/about/about_telemetry)
+topic to read details about telemetry gathered by PowerShell.
