 We want contributing to Gatsby to be fun, enjoyable, and educational for anyone and everyone. Contributions go far beyond pull requests and commits; we are thrilled to receive a variety of other contributions including the following:
 
 * Blogging, speaking about, or creating tutorials about one of Gatsby's many features. Mention @gatsbyjs on Twitter and/or email shannon [at] gatsbyjs [dot] com so we can give pointers and tips (if you want them :) and help you spread the word. Please add your blog posts and videos of talks to our [Awesome Gatsby](/docs/awesome-gatsby/) page.
+* [Submit new feature ideas through an RFC](/blog/2018-04-06-introducing-gatsby-rfc-process/)
 * Submitting new documentation; titles in _italics_ on gatsbyjs.org are stubs and need contributions
 * Tweeting about things you build with @gatsbyjs (make sure to @ mention us!)
 * Submitting documentation updates, enhancements, designs, or bugfixes

+title: "Introducing the Gatsby RFC Process"
+author: Kyle Mathews
+date: "2018-04-06"
+---
+
+We're adopting an RFC ("request for comments") process for contributing ideas to Gatsby. 
+
+Inspired by [React](https://github.com/reactjs/rfcs), [Yarn](https://github.com/yarnpkg/rfcs), [Ember](https://github.com/emberjs/rfcs), and [Rust](https://github.com/rust-lang/rfcs), the goal is to allow Gatsby core team members and community members to collaborate on the design of new features. It's also intended to provide a clear path for ideas to enter the project:
+
+- Create an RFC document detailing your proposal.
+- Submit a PR to the [RFC repository](https://github.com/gatsbyjs/rfcs).
+- Incorporate feedback into the proposal.
+- After discussion, the core team may or may not accept the RFC.
+- If the RFC is accepted, the PR is merged.
+
+RFCs are accepted when they are approved for implementation in Gatsby. A more thorough description of the process is available in the repository's [README](https://github.com/gatsbyjs/rfcs/blob/master/README.md). The exact details may be refined in the future.
+
+## Who Can Submit RFCs?
+
+Anyone! No knowledge of Gatsby's internals is required, nor are you expected to implement the proposal yourself.
+
+## What Types of Changes Should Be Submitted As RFCs?
+
+Generally, any idea that would benefit from additional review or design before being implemented is a good candidate for an RFC. As a rule of thumb, this means any proposal that adds, changes, or removes a Gatsby API.
+
+Not every change must go through the RFC process. Bug fixes or performance improvements that don't touch the API can be submitted directly to the main library.
+
+## RFCs for a new GitHub labeling system and to remove our special layout component
+
+Coinciding with the launch of our RFC process, we've submitted a [proposal for a new GitHub labeling system](https://github.com/gatsbyjs/rfcs/pull/1) and a [proposal to remove our special layout component](https://github.com/gatsbyjs/rfcs/pull/2). Both proposals have already received many valuable comments from the community that we're incorporating into the design of the new process and API.
+
+Both PRs are good examples of how a typical RFC should be structured. We're excited to start receiving your proposals!
