-## TODO
+## When this process is followed
 
-The first RFC will define the process around RFCs.
+This process is followed when one intends to make "substantial" changes to the
+Nix ecosystem. What constitutes a "substantial" change is evolving based on
+community norms, but may include the following.
+
+* Any semantic or syntactic change to the language that is not a bugfix
+* Removing language features
+* Big restructuring of nixpkgs
+* Expansions to the scope of nixpkgs (new arch, major subprojects, ...)
+* Introduction of new interfaces or functions
+
+Certain changes do not require an RFC:
+
+* Adding, updating and removing packages in nixpkgs
+* Fixing security updates and bugs that don't break interfaces
+
+Pull requests that contain any of the afore mentioned 'substantial' changes may be closed if there is no RFC connected to the proposed changes.
+
+## Description of the process
+
+In short, to get a major feature added to the Nix ecosystem, one should first
+go through the RFC process in order to improve the likelyhood of inclusion.
+Here are roughly the steps that one would take:
+
+* Fork the RFC repo https://github.com/NixOS/rfcs
+* Copy `0000-template.md` to `rfcs/0000-my-feature.md` (where 'my-feature' is
+  descriptive. don't assign an RFC number yet).
+* Fill in the RFC
+* Submit a pull request. Rename the rfcs with the PR number. (eg: PR #123 would
+  be `rfcs/0123-my-feature.md`)
+
+At this point, the person submitting the RFC should find at least one "co-author"
+that will help them bring the RFC to completion. The goal is to improve the
+chances that the RFC is both desired and likely to be implemented.
+
+Once the author is happy with the state of the RFC, they should seek for
+wider community review by stating the readyness of the work. Advertisement on
+the mailing-list and IRC is an acceptable way of doing that.
+
+After a number of rounds of review the discussion should settle and a general
+consensus should emerge. This bit is left intentionally vague and should be
+refined in the future. We don't have a technical commitee so controversial
+changes will be rejected by default.
+
+If a RFC is accepted then authors may implement it and submit the feature as a
+pull request to the Nix or nixpkgs repo. An 'accepted' RFC is not a rubber
+stamp, and in particular still does not mean the feature will ultimately be
+merged; it does mean that in principle all the major stakeholders have agreed
+to the feature and are amenable to merging it.
+
+Whoever merges the RFC should do the following:
+
+* Fill in the remaining metadata in the RFC header, including links for the
+  original pull request(s) and the newly created issue.
+* Commit everything.
+
+If a RFC is rejected, whoever merges the RFC should do the following:
+* Move the rfc to the rejected folder
+* Fill in the remaining metadata in the RFC header, including links for the
+  original pull request(s) and the newly created issue.
+* Include a summary reason for the rejection
+* Commit everything
+
+## Role of the "co-author"
+
+The goal for assigning a "co-author" is to help move the RFC along.
+
+The co-author should:
+* be available for discussion with the main author
+* respond to inquiries in a timely manner
+* help with fixing minor issues like typos so community discussion can stay
+  on design issues
+
+The co-author doesn't necessarily have to agree with all the points of the RFC
+but should generally be satisfied that the proposed additions are a good thing
+for the community.
