+== Configuring the banner
+
+By default when a Quarkus application starts (in regular or dev mode), it will display an ASCII art banner. The banner can be disabled by setting `quarkus.banner.enabled=false` in `application.properties`,
+by setting the `-Dquarkus.banner.enabled=false` Java System Property, or by setting the `QUARKUS_BANNER_ENABLED` environment variable to `false`.
+Furthermore, users can supply a custom banner by placing the banner file in `src/main/resources` and configuring `quarkus.banner.path=name-of-file` in `application.properties`.
