+## Replaying the Event Stream
+
+This command will replay the event stream from an old event onward. The server will replay all the cached events if the ID is 0 or if you specify an event ID already purged from the node's cache.
+
+Replace the `HOST`, `PORT`, and `ID` fields with the values needed.
+
+```sh
+curl -sN http://HOST:PORT/events?start_from=ID
+```
+
+**Example:**
+
+```sh
+curl -sN http://65.21.235.219:9999/events?start_from=29267508
+```
+
+Note that certain shells like `zsh` may require an escape character before the question mark.

+## Configuring the Sidecar
 
 The file `/etc/casper-sidecar/config.toml` holds a default configuration. This should work if installed on a Casper node.
 
 If you install the Sidecar on an external server, you must update the `ip-address` values under `node_connections` appropriately.
 
 For more information, including how to setup the SSE, RPC, REST, and Admin servers, read the [configuration options](../README.md#configuring-the-sidecar) in the main README.
