 Use the `jobs` property to control how many jobs will get executed simultaneously.
 On Linux, specify `-Pjobs=$(nproc)`. Defaults to `8`.
+#### Rendering
+You can use the `renderingPlatform` property to control which rendering platform to initialize for.
 #### JVM Home
 You can use the `graalHome` property to specify the `$JAVA_HOME` of your local GraalVM installation.
