 Depending on your setup, you might end up running a different version than the one displayed with `java -version`.
 If you get strange errors such as `Unsupported major.minor version` and you were expecting to run a JDK11 or newer, you might want to explicitly set the `JAVA_HOME` env variable.

 The bundle structure is as follows:
 
-* `bin`: launch scripts for Gatling and the Recorder.
-* `conf`: configuration files for Gatling, Akka and Logback.
-* `lib`: Gatling and dependencies binaries
-* `user-files`:
-    * `simulations`: where to place your Simulations code. You must respect the package folder hierarchy.
-    * `resources`: non source code files such as feeder files and templates for request bodies.
-    * `lib`: you can add you own dependencies (JAR files) here. When running on Gatling Enterprise, they are packaged in a single "fat JAR" file together with your Simulations code.
-* `results`: where test results are generated.
