Thanks for your translation! Do you happen to know anyone who understands Nepali and can review your translated content? I can't read it unfortunately 😅

@stevhliu I have reviewed the entire translated text. Each step is clearly explained, and I can understand every word without any confusion. Is there anything else you'd like me to do?
