+## Quick Start
+
+The provided `Dockerfile` will compile and build the server application.  Use a bind mount to store the SQLite database outside of the container image, and map the container's 8080 port to a host port (8090 in the example below).
+
+```console
+$ docker build -t nostr-rs-relay .
+$ docker run -p 8090:8080 --mount src=$(pwd)/nostr_data,target=/usr/src/app/db,type=bind nostr-rs-relay
+```
+
+Use a `nostr` client such as [`noscl`](https://github.com/fiatjaf/noscl) to publish and query events.
+
+```console
+$ noscl publish "hello world"
+Sent to 'ws://localhost:8090'.
+Seen it on 'ws://localhost:8090'.
+$ noscl home
+Text Note [81cf...2652] from 296a...9b92 5 seconds ago
