 - Check which regressions can be closed as "accepted". Add a comment clarifying that the PR causing the regression is accepted as breaking change, example: "Closing since PR #123456 will be mentioned in the release notes". Check carefully, don't be trigger-happy. Discussions and comments about this practice can be directed on [Zulip](https://rust-lang.zulipchat.com/#narrow/channel/242269-t-release.2Ftriage/topic/beta.20regressions.20that.20are.20no.20more/near/456509338).
 
+## Meetings
+
+T-compiler has two kinds of meetings: triage and deisng meetings. Triage meetings happen weekly, there is a [tool](https://github.com/rust-lang/triagebot/commit/bc82955ff15f69571bcc47d2efbfc9d4f7a6dabb) to generate 80% of the meeting's agenda. Design meetings are proposed on the [T-compiler repository](https://github.com/rust-lang/compiler-team/issues?q=sort%3Aupdated-desc%20is%3Aissue%20is%3Aopen%20label%3Ameeting-proposal) and scheduled during recurrent *steering* meetings (where the next *design* meetings are scheduled). Design meetings also need an agenda and a bit of work to summarize the topic and bring together documentation, invite relevant people and so on.
