What's wrong? 🤔

[rerorero]

Okay, I will revisit it once you update the documents.

@rerorero Sorry, I forgot to reply. The docs have been updated already a while ago. Would you like to have a look again?

[rerorero]

Thank you for letting me know, let me take a look again.

[rerorero]

@kzhirata Thank you for taking a look, I updated according to your comments.
