-Submitting Proposals
-====================
-
-You can request a new feature or submit a proposal by submitting an issue to
-our GitHub Repository.
-If you would like to implement a new feature, please submit an issue with a
-proposal (RFC) for your work first, to be sure that we can use it. Please
-consider what kind of change it is:
-
-* For a Major Feature, first open an issue and outline your proposal so that it
-  can be discussed. This will also allow us to better coordinate our efforts,
-  prevent duplication of work, and help you to craft the change so that it is
-  successfully accepted into the project. Providing the following information
-  will increase the chances of your issue being dealt with quickly:
-
-  * Overview of the Proposal
-  * Motivation for or Use Case
-  * Design Details
-  * Alternatives
-  * Test Strategy
-
-* Small Features can be crafted and directly submitted as a Pull Request.
