Starting with NL6621 wifi module with Arduino Uno

I surfed the Internet but I don't find an example to start with NL6621 (NL6621-Y1). I want only an example and how to setup it using Arduino Uno.

I just found a Chinese PDF that I don't understand it. Even translating it to English is useless.
Btw, there are some sdk at github.

I really appreciate your answers.

I'm in the same boat, does someone can help?

Thank you.
