+The default image uses Eclipse Temurin (OpenJDK) 25. The Java runtime is not
+supported on 32-bit ARM (armhf) — no upstream Temurin 25 build exists for that

 If you have dependencies in other packages, create a fat/uber Jar with all the
 dependencies. We currently do not support maven/sbt/ant/... builds
 
 ### Building the SDK

+The SDK jar is compiled for Java 25 bytecode. Build it with JDK 25+.
