I made a rough draft for the contribution.
I didn't ask my native friends to check my English, so my English is awful here, so sorry!!!
By Jan.1st, I will brush up my concept and my English sentences.
I'll put 2~3 movement for my 1st issue (Jan.4th), but for the first issue, I think to clarify my purpose is the most important thing.
Please give me your feedback and some advice.
