 You'll also need _git_ so the Makefile can clone the FreeRTOS-Kernel repository. We assume you have it since you got to get this repository somehow. If you don't, and don't want to install it, just get the proper [FreeRTOS-Kernel](https://github.com/FreeRTOS/FreeRTOS-Kernel) version (see the Makefile) from its repository, as you did with the Mongoose repository.
