Hi Beisi could you help review this PR? Thanks

It would be better if gives some help messages

[isra-fel]

The common practice is to write parameter description (aka help message) in the [Parameter()] attribute. When generating help it will be written to the markdown files.

However it's also OK (though not recomended) to manually update the help file.

Understood. Thank you.

I will make some updates and submit a PR fixing that
