 ## Contribution Guidelines
 
-Feel free to put up a pull request to fix a bug or maybe add a feature. I will
-give it a code review and make sure that it does not break backwards
-compatibility. If I or any other collaborators agree that it is in line with
-the vision of the project, we will work with you to get the code into
-a mergeable state and merge it into the master branch.
-
-If you have contributed something significant to the project, we will most
-likely add you as a collaborator. As a collaborator you are given the ability
-to merge others pull requests. It is very important that new code does not
-break existing code, so be careful about what code you do choose to merge.
-
-If you feel like you have contributed to the project but have not yet been
-added as a collaborator, we probably forgot to add you, please open an issue.
