Compiling Haiku for RISCV64?

https://download.haiku-os.org/nightly-images/riscv64/

Where is the guide for compiling Haiku for RISCV64?

No one has written one yet, apparently: https://www.haiku-os.org/guides/building

Instruction with cross build tools should work. Just replace architecture to riscv64.

Thank you for tip.
