 ## Workflow labels
 
-Labelling issues is described in the [GitLab Inc engineering workflow].
+To allow for asynchronous issue handling, we use [milestones][milestones-page]
+and [labels][labels-page]. Leads and product managers handle most of the
+scheduling into milestones. Labelling is a task for everyone.
 
-## Implement design & UI elements
+Most issues will have labels for at least one of the following:
 
-Please see the [UX Guide for GitLab].
+- Type: ~"feature proposal", ~bug, ~customer, etc.
+- Subject: ~wiki, ~"container registry", ~ldap, ~api, etc.
+- Team: ~CI, ~Discussion, ~Edge, ~Frontend, ~Platform, etc.
+- Priority: ~Deliverable, ~Stretch
+
+All labels, their meaning and priority are defined on the
+[labels page][labels-page].
+
+If you come across an issue that has none of these, and you're allowed to set
+labels, you can _always_ add the team and type, and often also the subject.
+
+[milestones-page]: https://gitlab.com/gitlab-org/gitlab-ce/milestones
+[labels-page]: https://gitlab.com/gitlab-org/gitlab-ce/labels
+
+### Type labels (~"feature proposal", ~bug, ~customer, etc.)
+
+Type labels are very important. They define what kind of issue this is. Every
+issue should have one or more.
+
+Examples of type labels are ~"feature proposal", ~bug, ~customer, ~security,
+and ~"direction".
+
+A number of type labels have a priority assigned to them, which automatically
+makes them float to the top, depending on their importance.
+
+Type labels are always lowercase, but can have any color, besides blue (which is
+already reserved for subject labels).
+
+The descriptions on the [labels page][labels-page] explain what falls under each type label.
+
+### Subject labels (~wiki, ~"container registry", ~ldap, ~api, etc.)
+
+Subject labels are labels that define what area or feature of GitLab this issue
+hits. They are not always necessary, but very convenient.
+
+If you are an expert in a particular area, it makes it easier to find issues to
+work on. You can also subscribe to those labels to receive an email each time an
+issue is labelled with a subject label corresponding to your expertise.
+
+Examples of subject labels are ~wiki, ~"container registry", ~ldap, ~api,
+~issues, ~"merge requests", ~labels, and ~"container registry".
+
+Subject labels are always colored blue and all-lowercase.
+
+### Team labels (~CI, ~Discussion, ~Edge, ~Frontend, ~Platform, etc.)
+
+Team labels specify what team is responsible for this issue.
+Assigning a team label makes sure issues get the attention of the appropriate
+people.
 
-## Release retrospective and kickoff
+The current team labels are ~Build, ~CI, ~Discussion, ~Documentation, ~Edge,
+~Frontend, ~Gitaly, ~Platform, ~Prometheus, ~Release, and ~"UX".
 
-### Retrospective
+The descriptions on the [labels page][labels-page] explain what falls under the
+responsibility of each team.
 
-After each release, we have a retrospective call where we discuss what went well,
-what went wrong, and what we can improve for the next release. The
-[retrospective notes] are public and you are invited to comment on them.
-If you're interested, you can even join the
-[retrospective call][retro-kickoff-call], on the first working day after the
-22nd at 6pm CET / 9am PST.
+Team labels are always colored aqua, and are capitalized so that they show up as
+the first label for any issue.
 
-### Kickoff
+### Priority labels (~Deliverable and ~Stretch)
 
-Before working on the next release, we have a
-kickoff call to explain what we expect to ship in the next release. The
-[kickoff notes] are public and you are invited to comment on them.
-If you're interested, you can even join the [kickoff call][retro-kickoff-call],
-on the first working day after the 7th at 6pm CET / 9am PST..
+Priority labels help us clearly communicate expectations of the work for the
+release. There are two levels of priority labels:
 
-[retrospective notes]: https://docs.google.com/document/d/1nEkM_7Dj4bT21GJy0Ut3By76FZqCfLBmFQNVThmW2TY/edit?usp=sharing
-[kickoff notes]: https://docs.google.com/document/d/1ElPkZ90A8ey_iOkTvUs_ByMlwKK6NAB2VOK5835wYK0/edit?usp=sharing
-[retro-kickoff-call]: https://gitlab.zoom.us/j/918821206
+- ~Deliverable: Issues that are expected to be delivered in the current
+  milestone.
+- ~Stretch: Issues that are a stretch goal for delivering in the current
+  milestone. If these issues are not done in the current release, they will
+  strongly be considered for the next release.
+
+### Label for community contributors (~"Accepting Merge Requests")
+
+Issues that are beneficial to our users, 'nice to haves', that we currently do
+not have the capacity for or want to give the priority to, are labeled as
+~"Accepting Merge Requests", so the community can make a contribution.
+
+Community contributors can submit merge requests for any issue they want, but
+the ~"Accepting Merge Requests" label has a special meaning. It points to
+changes that:
+
+1. We already agreed on,
+1. Are well-defined,
+1. Are likely to get accepted by a maintainer.
+
+We want to avoid a situation when a contributor picks an
+~"Accepting Merge Requests" issue and then their merge request gets closed,
+because we realize that it does not fit our vision, or we want to solve it in a
+different way.
+
+We add the ~"Accepting Merge Requests" label to:
+
+- Low priority ~bug issues (i.e. we do not add it to the bugs that we want to
+solve in the ~"Next Patch Release")
+- Small ~"feature proposal" that do not need ~UX / ~"Product work", or for which
+the ~UX / ~"Product work" is already done
+- Small ~"technical debt" issues
+
+After adding the ~"Accepting Merge Requests" label, we try to estimate the
+[weight](#issue-weight) of the issue. We use issue weight to let contributors
+know how difficult the issue is. Additionally:
+
+- We advertise [~"Accepting Merge Requests" issues with weight < 5][up-for-grabs]
+  as suitable for people that have never contributed to GitLab before on the
+  [Up For Grabs campaign](http://up-for-grabs.net)
+- We encourage people that have never contributed to any open source project to
+  look for [~"Accepting Merge Requests" issues with a weight of 1][firt-timers]
+

 ## Assigning issues
 
 If an issue is complex and needs the attention of a specific person, assignment is a good option but assigning issues might discourage other people from contributing to that issue. We need all the contributions we can get so this should never be discouraged. Also, an assigned person might not have time for a few weeks, so others should feel free to takeover.
