+# About the compiler team
+
+rustc is maintained by the
+[Rust compiler team](https://www.rust-lang.org/en-US/team.html). The
+people who belong to this team collectively work to track regressions
+and implement new features. Members of the Rust compiler team are
+people who have made significant contributions to rustc and its
+design.
+
+## Rust compiler meeting
+
+The compiler team has a weekly meeting where we do triage and try to generally
+stay on top of new bugs, regressions, and other things. This general plan for
+this meeting can be found in [the rust-compiler-meeting etherpad][etherpad]. It works
+roughly as follows:
+
+- **Review P-high bugs:** P-high bugs are those that are sufficiently important for us
+  to actively track progress. P-high bugs should ideally always have an assignee.
+- **Look over new regressions:** we then look for new cases where the
+  compiler broke previously working code in the wild. Regressions are
+  almost always marked as P-high; the major exception would be bug
+  fixes (though even there we often
+  [aim to give warnings first][procedure]).
+- **Check I-nominated issues:** These are issues where feedback from the team is desired.
+- **Check for beta nominations:** These are nominations of things to backport to beta.
+
+The meeting currently takes place on Thursdays at 10am Boston time
+(UTC-4 typically, but daylight savings time sometimes makes things
+complicated).
+
+The meeting is held over a "chat medium" -- it used to be IRC, but we
+are currently in the process of evaluating other alternatives. Check
+[the etherpad] to find the current home (and see
+[this internals thread][thread] for some ongoing discussion).

+
+## Team membership
+
+Membership in the Rust team is typically offered when someone has been
+making significant contributions to the compiler for some
+time. Membership is both a recognition but also an obligation:
+compiler team members are generally expected to help with upkeep as
+well as doing reviews and other work.
+
+If you are interested in becoming a compiler team member, the first
+thing to do is to start fixing some bugs, or get involved in a working
+group.
+
+### r+ rights
+
+Once you have made a number of individual PRs to rustc, we will often
+offer r+ privileges. This means that you have the right to instruct
+"bors" (the robot that manages which PRs get landed into rustc) to
+merge a PR
+([here are some instructions for how to talk to bors][homu-guide]).
+
+[homu-guide]: https://buildbot2.rust-lang.org/homu/
+
+The guidelines for reviewers are as follows:
+
+- You are always welcome to review any PR, regardless of who it is assigned to.
+  However, do not r+ PRs unless:
+  - You are confident in that part of the code.
+  - You are confident that nobody else wants to review it first.
+    - For example, sometimes people will express a desire to review a PR before it lands,
+      perhaps because it touches a particularly sensitive part of the code.
+- Always be polite when reviewing: you are a representative of the Rust project,
+  so it is expected that you will go above and beyond when it comes to the [Code of Conduct].
+
+[Code of Conduct]: https://www.rust-lang.org/en-US/conduct.html
+
+### high-five
+
+Once you have r+ rights, you can also be added to the high-five
+rotation. high-five is the bot that assigns incoming PRs to
+reviewers. If you are added, you will be randomly selected to review
+PRs. If you find you are assigned a PR that you don't feel comfortable
+reviewing, you can also leave a comment like `r? @so-and-so` to assign
+to someone else -- if you don't know who to request, just write `r?
+@nikomatsakis for reassignment` and @nikomatsakis will pick someone
+for you.
+
+[hi5]: https://github.com/rust-highfive
+
+Getting on the high-five list is much appreciated as it lowers the
+review burden for all of us! However, if you don't have time to give
+people timely feedback on their PRs, it may be better that you don't
+get on the list.
+
+### Team membership
+
+Full team membership is typically extended once someone made many
+contributions to the Rust compiler over time, ideally (but not
+necessarily) to multiple areas. Sometimes this might be implementing a
+new feature, but it is also important -- perhaps more important! -- to
+have time and willingness to help out with general upkeep such as
+bugfixes, tracking regressions, and other less glamorous work.
