@sijie I first added a Chinese-related document of How to add a new command. After the content is determined, I will translate it into a related English document.

[sijie]

the Chinese version of developer guide looks good to me. Please add the english version. Once you add the english version, please loop in Yu for reviewing it.

@jennifer88huang @Anonymitaet This pull request is about the documentation, please help confirm the language organization and grammar issues.

Thanks.

@Anonymitaet Could you please help review this PR? Thank you.

[Anonymitaet]

@jennifer88huang glad to help

@wolfstudy I've finished my review but failed to submit.

I've tried many times but it always shows:

Will try later.

[Anonymitaet]

I've tried several times (including change a web browser to submit) but failed again.

I found that many people have encountered this problem as well, but GitHub does not provide a solution officially.

I've reported this issue to GitHub and waiting for a response.

@Anonymitaet Is it convenient to copy your review comments to google docs as screenshots? Or you can try to split your comments.

[Anonymitaet]

@wolfstudy I've tried several methods to capture a scrolling screenshot but all failed, I guess the reason is that this file is too large (112 comments).
I can give you my GitHub account and password, could you please log in and check my suggestions?

@Anonymitaet done, PTAL again.

[Anonymitaet]
