+# Building on ARM
 
+Linux is currently supported. MacOS & Windows can use a Linux VM, host must be a compatible ARM CPU with AArch64. Use the Linux build procedure with the following modifications:
+
+Add `-flax-vector-conversions` to CFLAGS, or use `./arm-build.sh`.
+AES and SHA2 will automatically be compiled if the CPU supports them or they can be selected manually. See armbuild-all.sh for examples.
