Directories:



+ The FreeRTOS/Source directory contains the FreeRTOS source code, and contains

  its own readme file.



+ The FreeRTOS/Demo directory contains a demo application for every official

FreeRTOS port, and contains its own readme file.



+ See http://www.freertos.org/a00017.html for full details of the directory 

  structure and information on locating the files you require.



The easiest way to use FreeRTOS is to start with one of the pre-configured demo 

application projects (found in the FreeRTOS/Demo directory).  That way you will

have the correct FreeRTOS source files included, and the correct include paths

configured.  Once a demo application is building and executing you can remove

the demo application file, and start to add in your own application source

files.
