+LLAMARA backend is able to serve a JavaScript Single-Page-Application, such as a React, Vue, or Angular application, as its frontend.
 
 To do so, you need to place the build output of your bundler, e.g. Webpack or Vite, into the [`META-INF/resources`](src/main/resources/META-INF/resources) folder during build-time of LLAMARA backend.
 The bundled JavaScript SPA will then be part of the build JAR and automatically served by Quarkus on the applications root path.
