-The power actions below require an in-band agent, Local Management Service (LMS), or Intel® Integrated Management and Security Status (Intel® IMSS).
+The following power actions require Intel Local Manageability Service (LMS) to be installed and running.
 
-LMS is a service that runs locally on an Intel AMT device and enables local management applications to send requests and receive responses to and from the device. The LMS  listens for and intercepts requests directed to the Intel AMT local host and routes them to to the Management Engine via the Intel Management Engine Interface (MEI) driver.

 !!! Info "Installing LMS and Drivers"
-    The service installer is packaged with the Intel MEI drivers on the OEM websites. If Windows OS is reimaged or reinstalled, only the Intel MEI Driver is reinstalled, not LMS or IMSS.
-    
-    If the LMS is not installed, visit the OEM website and look for download packages for Intel® IMSS or the Intel CSME driver.
+    **Windows:** LMS is typically included in OEM Intel CSME driver packages available from your system manufacturer's support site. After reinstalling the OS, ensure you install the complete CSME driver package (not just the MEI driver).
+
+    **Linux:** Build LMS from source using the [Intel LMS repository](https://github.com/intel/lms). Ensure the MEI driver is installed first. See the repository's build instructions for dependencies and compilation steps.
