 This Code of Conduct is adapted from the [Contributor Covenant][contributor-covenant], version 1.1.0,
 available at [http://contributor-covenant.org/version/1/1/0/](http://contributor-covenant.org/version/1/1/0/).
 
+## Contribution Flow
+
+When contributing to GitLab, your merge request is subject to review by merge request maintainers of a particular specialty.
+
+When you submit code to GitLab, we really want it to get merged, but there will be times when it will not be merged.
+
+When maintainers are reading through a merge request they may request guidance from other maintainers. If merge request maintainers conclude that the code should not be merged, our reasons will be fully disclosed. If it has been decided that the code quality is not up to GitLab’s standards, the merge request maintainer will refer the author to our docs and code style guides, and provide some guidance.
+
+Sometimes style guides will be followed but the code will lack structural integrity, or the maintainer will have reservations about the code’s overall quality. When there is a reservation the maintainer will inform the author and provide some guidance.  The author may then choose to update the merge request. Once the merge request has been updated and reassigned to the maintainer, they will review the code again. Once the code has been resubmitted any number of times, the maintainer may choose to close the merge request with a summary of why it will not be merged, as well as some guidance. If the merge request is closed the maintainer will be open to discussion as to how to improve the code so it can be approved in the future.
+
+GitLab will do its best to review community contributions as quickly as possible. Specially appointed developers review community contributions daily. You may take a look at the [team page](https://about.gitlab.com/team/) for the merge request coach who specializes in the type of code you have written and mention them in the merge request.  For example, if you have written some JavaScript in your code then you should mention the frontend merge request coach. If your code has multiple disciplines you may mention multiple merge request coaches.
+
+GitLab receives a lot of community contributions, so if your code has not been reviewed within 4 days of its initial submission feel free to re-mention the appropriate merge request coach.
+
+When submitting code to GitLab, you may feel that your contribution requires the aid of an external library. If your code includes an external library please provide a link to the library, as well as reasons for including it.
+
+When your code contains more than 500 changes, any major breaking changes, or an external library, `@mention` a maintainer in the merge request. If you are not sure who to mention, the reviewer will add one early in the merge request process.

-## Feature Freeze
+## Feature freeze on the 7th for the release on the 22nd
 
-After the 7th (Pacific Standard Time Zone) of each month, RC1 of the upcoming release is created and deployed to GitLab.com and the stable branch for this release is frozen, which means master is no longer merged into it.
+After the 7th (Pacific Standard Time Zone) of each month, RC1 of the upcoming release (to be shipped on the 22nd) is created and deployed to GitLab.com and the stable branch for this release is frozen, which means master is no longer merged into it.
 Merge requests may still be merged into master during this period,
 but they will go into the _next_ release, unless they are manually cherry-picked into the stable branch.
 By freezing the stable branches 2 weeks prior to a release, we reduce the risk of a last minute merge request potentially breaking things.
 
+### Between the 1st and the 7th
+
+These types of merge requests for the upcoming release need special consideration:
+
+* **Large features**: a large feature is one that is highlighted in the kick-off
+  and the release blogpost; typically this will have its own channel in Slack
+  and a dedicated team with front-end, back-end, and UX.
+* **Small features**: any other feature request.
+
+**Large features** must be with a maintainer **by the 1st**. This means that:
+
+* There is a merge request (even if it's WIP).
+* The person (or people, if it needs a frontend and backend maintainer) who will
+  ultimately be responsible for merging this have been pinged on the MR.
+
+It's OK if merge request isn't completely done, but this allows the maintainer
+enough time to make the decision about whether this can make it in before the
+freeze. If the maintainer doesn't think it will make it, they should inform the
+developers working on it and the Product Manager responsible for the feature.
+
+The maintainer can also choose to assign a reviewer to perform an initial
+review, but this way the maintainer is unlikely to be surprised by receiving an
+MR later in the cycle.
+
+**Small features** must be with a reviewer (not necessarily maintainer) **by the
+3rd**.
+
+Most merge requests from the community do not have a specific release
+target. However, if one does and falls into either of the above categories, it's
+the reviewer's responsibility to manage the above communication and assignment
+on behalf of the community member.
+
+### On the 7th
+
+Merge requests should still be complete, following the
+[definition of done][done]. The single exception is documentation, and this can
+only be left until after the freeze if:
+
+* There is a follow-up issue to add documentation.

 and security issues will be cherry-picked into the stable branch.
 Any merge requests cherry-picked into the stable branch for a previous release will also be picked into the latest stable branch.
