 Clone this project in order to create your own jPOS based application.
 
+The template ships with a `.sdkmanrc` file that pins Java 25.0.1-amzn and Gradle 9.4.0 so every shell can run `sdk env install && sdk env` to reproduce the toolchain.
+It also applies the published `org.jpos.jposapp` Gradle plugin (v0.0.16), which replaces the legacy `jpos-app.gradle` helper and provides the `installApp`, `dist`, `distnc`, `zip`, and `run` tasks out of the box.
+
 We recommend that you install [Gradle](http://gradle.org/) in order to build your jPOS projects, but if you don't have it installed, you can use the Gradle wrapper scripts `gradlew` and `gradlew.bat`. In the following instructions, when we say `gradle` we really mean either your installed Gradle or one of the wrapper scripts (depending if you are on Unix or DOS based platforms).
