+## What has been deployed
+
+There are a few ways of checking what has been deployed to any environment on a specific day:
+1. In Slack
+2. In Grafana
+
+### Slack
+Check `#announcements` channel. `Deployer` bot announces all pipelines to all environments.
+Each message contains version that has been deployed. You can click on `deployer pipeline` link
+to view further details.

+
+### Grafana
+There are different dashboards that contain deployment information.
+One of them is `GitLab Triage`: https://dashboards.gitlab.net/d/RZmbBr7mk/gitlab-triage
