@ -147,6 +147,7 @@ To submit your own implementation to 1BRC, follow these steps:
* Make that implementation fast. Really fast.
* Create a copy of _calculate_average_baseline.sh_, named _calculate\_average\_<your_GH_user>.sh_, e.g. _calculate\_average\_doloreswilson.sh_.
* Adjust that script so that it references your implementation class name. If needed, provide any JVM arguments via the `JAVA_OPTS` variable in that script.
Make sure that script does not write anything to standard output other than calculation results.
* OpenJDK 21 is the default. If a custom JDK build is required, include the SDKMAN command `sdk use java [version]` in the launch shell script prior to application start.
* (Optional) If you'd like to use native binaries (GraalVM), adjust the _pom.xml_ file so that it builds that binary.
* Run the test suite by executing _/test.sh <your_GH_user>_; if any differences are reported, fix them before submitting your implementation.
