+# ARM support
+
+The ARM support should be considered experimental. It will be extended step by step in the coming weeks.
+
+Building a Docker Development Image works in the same fashion as for Intel platform (x86-64).
+Currently we have initial support for 32bit ARMv7 devices.
+
+To work with the Docker Development Image you have to clone the Docker/Docker repo on a supported device.
+It needs to have a Docker Engine installed to build the Docker Development Image.
+
+From the root of the Docker/Docker repo one can use make to execute the following make targets:
+- make validate
+- make binary
+- make build
+- make deb
+- make bundles
+- make default
+- make shell
+- make test-unit
+- make test-integration-cli
+- make
+
+The Makefile does include logic to determine on which OS and architecture the Docker Development Image is built.
+Based on OS and architecture it chooses the correct Dockerfile.
+For the ARM 32bit architecture it uses `Dockerfile.armhf`.
+
+So for example in order to build a Docker binary one has to  
+1. clone the Docker/Docker repository on an ARM device `git clone git@github.com:docker/docker.git`  
+2. change into the checked out repository with `cd docker`  
+3. execute `make binary` to create a Docker Engine binary for ARM
