 # Booking Service Demo
 
-This project uses Kotlin and Quarkus, the Supersonic Subatomic Framework.
+This project is intended for demonstration purposes. It proposes a [Solution](./solution.md) to an example [Problem](./problem.md).
 
-If you want to learn more about Quarkus, please visit its website: <https://quarkus.io/>.
+The application is a GraphQL API writen in Kotlin and Quarkus. It uses Postgres for persistence.
 
+To learn more about this project and try it out, continue reading.
