Thank for you great work!

Anyway, I have some problem, due to my poor programming background, I do not know how to run this file. For example, how to call it in terminal (step by step)? I need your guidance badly. :(
Thanks.

[Note: I read your blog (of course I use google translate), but I still not able to understand.]
