Hi! I have placed the specific document under docs/design and also pushed the code for the second time. Do I need to submit a new PR for the code? @hnwyllmm

It's OK. But it takes time to review the design. I'll start the work at the next week Thursday.

The code is too larger so we need more time to review it.
Maybe we can wait next week.
