 The easiest way to use version 4.0.0 and later of FreeRTOS-Plus-TCP is to refer the Getting started Guide (found [here](https://github.com/FreeRTOS/FreeRTOS-Plus-TCP/blob/main/GettingStarted.md))
 Another way is to start with the pre-configured IPv4 Windows Simulator demo (found in [this directory](https://github.com/FreeRTOS/FreeRTOS/tree/main/FreeRTOS-Plus/Demo/FreeRTOS_Plus_TCP_Minimal_Windows_Simulator)) or IPv6 Multi-endpoint Windows Simulator demo (found in [this directory](https://github.com/FreeRTOS/FreeRTOS/tree/main/FreeRTOS-Plus/Demo/FreeRTOS_Plus_TCP_IPv6_Demo/IPv6_Multi_WinSim_demo)). 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 files, and start to add in your own application source files.  See the [FreeRTOS Kernel Quick Start Guide](https://www.freertos.org/FreeRTOS-quick-start-guide.html) for detailed instructions and other useful links.
