+# Real time streaming example
+
+## Installation
+
+First you will need the nats cli, it is only required if you actually want to send some events
+
+```bash
+go install github.com/nats-io/natscli/nats@latest  
+```
+
+Now to spin up the resources:
+
+```bash
+docker compose up -d
+```
+
+Now to sign in with nats
+
+```bash
+nats context add real-time  
+# This creates a file in ~/.config/nats/real-time.json
+# Edit that and set username and password to `natsadmin`
+nats ctx select real-time
+```
+
+And subscribe with nats
+
+```bash
+nats sub cli.demo  
+```
+
+In a new terminal publish events
+
+```bash
+nats pub cli.demo '{"key":"value"}' --count=0 # count 0 will send a lot of events
+```
+
+Now open your client of choice: I used datagrip with default settings, simply add port 8123 and localhost and you should be good.
+
+The table will be in default called daily. It will contain a column key, with a bunch of rows with the value: `value`
