Fixed donation link.

Thanks for a nice project :)! Also I have a question, as I understand react-ast is a bit similar to babel template. I’m working on code transformer 🐊Putout and wandering is react ast can be used for plugins development.

The thing is most of the cases are pretty short, is hurd to imaging a lot of very big transforms in different code based… Anyways I like the idea, it’s very good :)!

Also as I see there is no 1 x 1 equality to Babel AST, am I right?
