 **JSON-Serialized GCN Notices Types in GCN Kafka:**
 
+Einstein Probe distributes alerts for the detection of gamma-ray transients. These notices are published on the GCN Kafka topic `gcn.notices.einstein_probe.wxt.alert`.
+
+The [GCN schema](/schema/stable/gcn/notices/einstein_probe/wxt/alert.schema.json) and
+example [JSON message](/schema/stable/gcn/notices/einstein_probe/wxt/alert.schema.example.json) files are available to use for [Einstein Probe Schema](/schema/stable/gcn/notices/einstein_probe). See the [Schema Browser](/docs/schema/stable/gcn/notices/einstein_probe/wxt/alert.schema.json) for more information on the properties defined in the schema.
+
+Detailed description and examples of EP Notices are available in the [GCN Schema GitHub project](https://github.com/nasa-gcn/gcn-schema/tree/main/gcn/notices/einstein_probe/wxt).
