The FreeRTOS/Source/ contains the FreeRTOS kernel source code, and contains its own readme file.
FreeRTOS/Source/include/ contains header files.
FreeRTOS/Source/portable/ contains processor architecture-specific files. (Various compiler directories each of which contains various processor architecture-specific files. We'll be using GCC compiler only!)
Everything else in the FreeRTOS/Source/ is the architecture-independent code.
The FreeRTOS/Demo/ contains a demo application for every official FreeRTOS port (i.e., various MCUs), and contains its own readme file.
The FreeRTOS/Test/ contains the tests performed on common code and the portable layer code, and contains its own readme file.
The FreeRTOS/License/ contains the license file that allows you to use the FreeRTOS kernel.
FreeRTOS-Plus/ contains various other middleware which can be used with FreeRTOS kernel such as CLI, IO, TCP, UDP, etc. (We'll not care about this contents.)
See FreeRTOS/SourceOrganization 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.
