+### ARM Binaries
+
+ARM compatibilty is considered experimental. Static binaries for ARM-based machines are cross-compiled within a Holy Build Box container using the [musl toolchain](https://musl.cc/).

+### ARM Compile Notes
+
+Compilation of ARM-compatible binaries requires additional environment variables to identify the proper musl toolchain and architecture to target for cross-compilation.
+
+**Compiling 64-bit binaries**:
+
+```sh
+docker run -t -i --rm -v `pwd`:/io --env ARCH=aarch64 --env CROSS=aarch64-linux-musl --env HOST=aarch64-linux-gnu phusion/holy-build-box-64:latest bash /io/compile-arm.sh
+```
+
+**Compiling 32-bit binaries**:
+
+```sh
+docker run -t -i --rm -v `pwd`:/io --env ARCH=arm --env CROSS=arm-linux-musleabihf --env HOST=arm-linux-gnueabihf phusion/holy-build-box-64:latest bash /io/compile-arm.sh
+```
+
+64-bit (aarch64) and 32-bit (arm) binaries will be placed in the current directory.
