yeah! one more attempt to fix readme

Hi! Thanks for creating and maintaining this gem.

I know many have attempted to make the readme be pleasant and all of them failed. I'm suggesting with my commit to create a symlink that will make it, and also won't add problems for mantainability because it will have the same content of the README.txt.

Hope it won't break anything and that we can have a beautiful readme on github :heart: 

PS. Please don't be rude to me
