It's too small

It was a short and concise lecture. I hope the selling and buying lectures will continue to be updated.

great.

Thank you^^ I am also touched by the sincerity in which you have organized the sources in github. I hope you will do the next lecture as well. It would be really great if you could upgrade the current lecture and teach us how to use it. Anyway, I am looking forward to the next lectures, so please keep updating them. Thank you^^
