Hello James,

Thanks for your quick response.

>From what I understand, `rpi23-gen-image` repository is old so it cannot be
used for this project.
I think I should run Sugar on Raspberry Pi OS and identify what is
broken/bugs, so I can work on fixing them during my GSoC period.

I will also check out other debian image builders for Raspberry Pi
which can be leveraged to create Sugar OS images.

I would also request my mentors @walterbender and @alexperez  to see if my
understanding is correct and also discuss the hardware requirements to
extend the functionalities of existing activities like Turtle Blocks,
Measure, and Pippy.

Thanks and Best Regards
Simrann Arora
