Please add a license file

[unixorn]

I'd like to add this to awesome-zsh-plugins, but it doesn't have a license file.

Please add a license file - if you don't have one in mind, I recommend using choosealicense.com to help choose an appropriate one.

Thanks!

I am happy that someone like this theme and your collection is really good. In fact, the way I know astro, the origin of this theme, is your collection!
But this theme is base on astro, and until now, there are many lines of code directly form it. Since I can't find any license of astro, I can't choose a license for my own theme.
