+## Building locally
+
+If you want to make local modifications to these images for development purposes or just to customize the logic: 
+```
+git clone https://github.com/linuxserver/docker-heimdall.git
+cd docker-heimdall
+docker build \
+  --no-cache \
+  --pull \
+  -t linuxserver/heimdall:latest .
+```
+
+The ARM variants can be built on x86_64 hardware using `multiarch/qemu-user-static`
+```
+docker run --rm --privileged multiarch/qemu-user-static:register --reset
+```
+
+Once registered you can define the dockerfile to use with `-f Dockerfile.aarch64`.
