++ The **FreeRTOS/Source** directory contains source code for some of the
+  FreeRTOS+ components.  These subdirectories contain further readme files and
+  links to documentation.
+
++ The **FreeRTOS/Demo** directory contains a demo application for every most of
+  the FreeRTOS+ components.  Lots of the demo applications use the FreeRTOS
+  Windows simulator for easy evaluation.  Be aware that FreeRTOS is much slower
+  and not deterministic when executed in a simulated environment.
+
++ The **FreeRTOS/Test** directory contains tests for some of the FreeRTOS+
+  components. These tests verify the functional correctness of FreeRTOS+ components.
+
++ The **FreeRTOS-Plus/VisualStudio_StaticProjects** directory contains configuration
+  files and Visual Studio projects for FreeRTOS components and some third party
+  libraries. These projects are used by the demo applications in the
+  FreeRTOS-Plus/Demo directory.
+
++ The **FreeRTOS-Plus/ThirdParty** directory contains third party libraries used by
+  the demo applications in the FreeRTOS-Plus/Demo directory.

-## Testing in FreeRTOS
-FreeRTOS (kernel and libraries) consists of common code and porting layer. Extensive [static analysis](https://en.wikipedia.org/wiki/Static_program_analysis) and [dynamic analysis](https://en.wikipedia.org/wiki/Dynamic_program_analysis) are done on both to ensure functional correctness of FreeRTOS.
-
-Additional bounded-ness checks are done using [CBMC](https://www.cprover.org/cbmc/). Although these checks do not cover all functions, they cover considerable chunk of code base. Missing CBMC tests will be added later.

 ## Directory structure
-This directory is in working progress -- we are migrating scattered test cases to this directory. Here only lists what's currently under this directory. 
 
-- ```./CBMC```: This directory contains automated proofs of the memory safety of various parts of the FreeRTOS code base.
-- ```./CMock```: This directory has the submoduled version of CMock for providing basis Unit testing
-- ```./Unit-Tests```: This directory has the Unit tests for FreeRTOS-Plus libraries. As of now, just Unit tests for +TCP (testing these).
+- ```./CMock```: This directory has the submoduled version of CMock for providing basis for Unit testing.
+- ```./FreeRTOS```-Cellular-Interface/Integration: This directory contains  integration tests for FreeRTOS-Cellular-Interface library.
+- ```./FreeRTOS-Plus```-TCP/Integration:  This directory contains integration tests for FreeRTOS-Plus_TCP library.
