 Right now all of our projects use streaming and
 we want to have an smooth migration so with this project we can replicate events
 on the jetstream side then remove them from streaming side.
+
+## How it works?
+
+It uses the configuration as below to first creates the stream on jetstream and then binds the given topics to it as subjects.
+then it starts subscribing on given topics from nats streaming and publishes them into jetstream.
+if you want to bind topics into different streams you need to run different instances of sjr.
