content: # This script uses QEMU emulation, so before execution pull the corresponding
  # images:
  #   docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
  
  # Usage(on repo root folder):
  #   docker build . --platform=linux/riscv64 --pull --no-cache --shm-size=196m -t darkfi:riscv -f ./contrib/docker/riscv2.Dockerfile -o riscv-bins
  # Optionally, add arguments like: --build-arg BINS=darkirc
  # If you want to keep building using the same builder, remove --no-cache option.

  #TODO: only darkirc has been tested, have to check rest binaries to add deps and ports.
