+# Setup
+
+## QEMU
+
+You most likely want to setup QEMU user-space emulation at the OS level to transparently execute RISC-V binaries on an x86-64 host.
+
+To do so, first install `rivos-sdk-qemu`:
+```
+sudo apt-get update
+sudo apt-get install -y rivos-sdk-qemu
+```
+
+Then, setup binfmt_mist with:
+```
+docker run --privileged --rm -v /rivos:/rivos -e QEMU_BINARY_PATH=/rivos/qemu/bin tonistiigi/binfmt --install riscv64
+```
