+## Dev
+
+You can run this application in dev mode using:
+
+```shell
+> mvn quarkus:dev
+```
+
+The application is exposed on `http://localhost:8080/`. 
+For example:
+
+```shell
+> curl http://localhost:8080/lorem
+```
+
+## Build

+# RESTEasy vs. RESTEasy Reactive Benchmark
+
+This directory contains three variants of the same _hello_ application:
+
+* [classic (RESTEasy classic)](./classic)
+* [reactive (RESTEasy reactive)](./reactive)
+* [reactive with blocking (RESTEasy reactive using a blocking signature)](./reactive-blocking)
+
+They all exposed the `/hello` endpoint.
+
+These applications are Quarkus applications.
+So you can run them in dev mode using `mvn quarkus:dev`, or package them using `mvn package`.
+To run the package, you need to package them, and then run them using: `java -jar target/quarkus-app/quarkus-run.jar`
+
+The benchmark use `wrk` (https://github.com/wg/wrk):
+
+```shell
+> wrk -t 10 -c50 -d40s http://localhost:8080/hello
