Hi, my name is Seunghun Bang.

Firstly, I would like to say thank you for your calendar.

There are many Koreans writing a number of blog posts of their projects using your calendar.
Thanks to your amazing project, many people are having their project more fancy. (Including me :) )

I thought it would be great if I can contribute to your project by translating README for Korean users.

Please take a look and I hope you have a great week!

Hey @a1603169! Thank you for your contribution. I'm worried about the maintenance though. How would I keep these docs up to date? I don't know Korean 🙈
