+## Support Links
+
+Support links let admins adjust the user dropdown menu to include links referring to internal company resources. The menu section replaces the original menu positions: documentation, report a bug to GitHub, or join the Discord server.
+
+![support links](../images/admin/support-links.png)
+
+Custom links can be set in the deployment configuration using the `-c <yamlFile>`
+flag to `coder server`.
+
+```yaml
+supportLinks:
+  - name: "On-call 🔥"
+    target: "http://on-call.example.internal"
+    icon: "bug"
+  - name: "😉 Getting started with Go!"
+    target: "https://go.dev/"
+  - name: "Community"
+    target: "https://github.com/coder/coder"
+    icon: "chat"
+```
+
+## Icons
+
+The link icons are optional, and limited to: `bug`, `chat`, and `docs`.
+
+## Service Banners (enterprise)
+
+Service Banners let admins post important messages to all site users. Only Site Owners may set the service banner.
+
+![service banners](../images/admin/service-banners.png)
