+However, Sofie is a big project with many differing users and use cases. **Larger changes** may be difficult to merge into an official repository if NRK and other contributors have not been made aware of their existence beforehand. Since figuring out what side-effects a new feature or a change may have for other Sofie users can be tricky, we advise opening an RFC issue (_Request for Comments_) early in your process. Good moments to open an RFC include:
+* When a user need is identified and described
+* When you have a rough idea about how a feature may be implemented
+* When you have a sketch of how a feature could look like to the user
+
+To facilitate timely handling of larger contributions, there’s a workflow intended to keep an open dialogue between all interested parties:
 
 1. Contributor opens an RFC (as a _GitHub issue_) in the appropriate repository.
 2. NRK evaluates the RFC, usually within a week.
-3. (If needed) NRK establishes contact with the RFC author, who will be invited to a workshop where the RFC is discussed. Meeting notes are published publicly on the RFC thread.
-4. The contributor references the RFC when a pull request is ready.
+3. If needed, NRK establishes contact with the RFC author, who will be invited to a workshop where the RFC is discussed. Meeting notes are published publicly on the RFC thread.
+4. Discussions about the RFC continue as needed, either in workshops or in comments in the RFC thread.
+5. The contributor references the RFC when a pull request is ready.
+
+It will be very helpful if your RFC includes specific use-cases that you are facing. Providing a background on how your users are using Sofie can clear up situations in which certain phrases or processes may be ambiguous. If during your process you have already identified various solutions as favorable or unfavorable, offering this context will move the discussion further still.
+
+Via the RFC process, we're looking to maximize involvement from various stakeholders, so you probably don't need to come up with a very detailed design of your proposed change or feature in the RFC. An end-user oriented description will be most valuable in creating a constructive dialogue, but don't shy away from also adding a more technical description, if you find that will convey your ideas better.
 
 ### Base contributions on the in-development branch
 In order to facilitate merging, we ask that contributions are based on the latest (at the time of the pull request) _in-development_ branch (often named `release*`).
