[afunTW]

Summary

Hi @bluet, inspired from #28, but we need to complete the following pre-work

• Revise the pack scripts setup.py
• Revise the dependency
• Clear codebase architecture and documentation
• Clear define how to contribute to this repo
• Roadmap
• Add coverage-test e.g. pytest-cov
• Add workflow to test package on different platforms e.g. Windows and macOS
• De-fork

regarding to setup.py scripts, maybe we should use poetry?

[bluet]

@a5r0n migrating to poetry would be nice 👍

[afunTW]

poetry is one of my potential solution, but we require to clarify the dependencies on all Python version we supported before doing so
