Add Major Section: Learning embedded Systems

[kammce]

This section will include links to other websites that explain the concept of the interface and how it's meant to be used. No need for us to rewrite the same content. (Still considering creating our own content as well with the links as further reading to keep everything in one place 🤔)

Then explain how to use it with libhal and best practices with the interface.

This section will also include information about FreeRTOS and other RTOS libraries, as well system architecture information.
