Aloha @nilisofficiel 🙌
Thanks for your contributions however I am not sure this one will pass.

Here are the feedback and reasons:

1. Your button's text is statically in french - this needs to be English first
2. The ideas is nice / but misleading UX wise:

• "submit" reflects the idea of being able to submit in-app / in-site an animation interactively.
  Whereas, here, the buttons is redirecting to the /CONTRIBUTIONS.md file - which does not exist in the project –Tips: always try to make sure your links are correct especially relative one - and check if the file exist.

This would be a great idea for another app oriented project (E.g.: app allowing the user to submit a contribution from the web page app).
However here, this is a repo to encourage developers to get their hands dirty, manipulating git, forking, github and coding while following the recommendation - to provide an experience of creating codebase addition.

In conclusion, this button doesn't convey with the current site here.
If any questions, feel free to reach out 🙌

Contente de voir tout de même un peu de contributions française :)
Happy coding !
