 ## About
-This project began with porting [MaterialKit][mdk], thanks [@nghialv][at-ng] for the great work!👍🖖
+This project began with porting [MaterialKit][], thanks [@nghialv][] for the great work!👍🖖
 
 But before long, I decided to rewrite all the components in JSX, with no or limited help of native code (the rewriting is in progress now).
 
-I figure that my life would be easier if I don’t have to do the porting again 😵, for the forthcoming *RN Android*. Although I have no idea how to provide it on *Android* for now, which is [MD][md]’s home field 😅.

 And lastly, it’s the very beginning of the project, lots of work to be done, ***contributions*** are welcome!🎉🍻
