+*** INTRODUCTION ***
+
+Development is now underway that will enable us to provide long-term support (LTS) 
+releases of FreeRTOS. An LTS release is maintained separately from the main 
+codebase. Typically, no new features are added after release, but critical bugs 
+and security vulnerabilities are patched for years after launch.
+
+We are currently working to improve modularity and memory usage of FreeRTOS 
+libraries to ensure the FreeRTOS LTS release helps our users cover a wider set of use cases.
+
+For additional details on LTS and the supported libraries,
+refer to https://freertos.org/ltsroadmap.html
+
+*** INSTRUCTIONS ***
+The pre-configured projects use the FreeRTOS kernel Windows port (often
+called the Windows simulator) to enable their evaluation using the free Visual
+Studio tools and without needing specific microcontroller hardware.
+
+Additional details can be found at: 
+https://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html
+
+Instructions for configuring and using the FreeRTOS IoT libraries are in the
+following links:
+
+  + https://www.FreeRTOS.org/mqtt/
+
+
+*** LOCATING THE EXAMPLE PROJECTS ***
+
+The Visual Studio projects for each of the FreeRTOS IoT library examples are
+located in sub-directories of the following top-level directories:
+
+  + /FreeRTOS-Plus/Demo/FreeRTOS-IoT-Libraries-LTS-Beta2/mqtt
+
+
+*** ADDITIONAL INFORMATION ***
+
+See http://www.freertos.org/a00017.html for full details of the FreeRTOS
+directory structure
