+### Mirroring status from upstream pipeline
+
+You can mirror the pipeline status from an upstream pipeline to a bridge job by
+using the `needs:pipeline` keyword. The latest pipeline status from master is
+replicated to the bridge job.
+
+Example:
+
+```yaml
+upstream_bridge:
+  stage: test
+  needs:
+    pipeline: other/project
+```
+
 ### Limitations
 
 Because bridge jobs are a little different to regular jobs, it is not
