Added some --help description text, and revised some hint text.

Workflow in development mode, Sync file and Clean Sync file are detailed in --help.

Time to update to PyPI 😄

I have drawn a flowchart.

You may be busy with other things~

Check it out if you have free time 😉

Thanks for doing this nice job! I've also checked the flowchart and it seems fine!
Would you please add flowchart to readme.md in dev mode instruction?

[Wind-stormger]

Which typography would be suitable, perhaps portrait?

[AmirHmZz]

Thanks! I think the landscape one is more compact and better to be viewed in desktop.

[Wind-stormger]

Done~

[AmirHmZz]

Thank you!
I've reviewed your flowchart. I think it might be better to create a flowchart for sync command separately and add it too readme in sync section! Also it is better to have the -clean flag in sync flowchart too.
