 Atom works better under Java 21 with virtual threads. Use the provided patch for Java 21.
 
+## Steps
+
 ```shell
 git apply --ignore-space-change --ignore-whitespace contrib/java21.patch
 sbt clean stage createDistribution
 ```
+
+## Consideration
+
+Atom performs well under Oracle GraalVM 21. When using this version, consider the terms of the [license](https://www.oracle.com/downloads/licenses/graal-free-license.html)
+
+If in doubt, use the image `ghcr.io/appthreat/atom` which is equally performant and uses the GraalVM Community Edition.
