+# React Server-Sent Events
+
+This is a library to send SSE events to a browser using ReactPHP.
+
+## Usage
+
+1. When receiving a request, create a new `NoccyLabs\React\Sse\EventSource` object.
+2. Return the `ResponseInterface` object from `$es->response()` to the client.
+3. Send your events using `$es->sendMessage()` and `$es->sendEvent()`.
+4. Use `$es->close()` to terminate the connection.
+5. Listen for the `close` event to know when it it time to discard the instance.
