+# Drone CI Setup Instructions for ARM/ARM64
+
+These are almost exactly the same as [for the regular Drone CI](https://github.com/rancher/os/wiki/How-to-set-up-RancherOS-CI), with only a couple differences:
+
+## 1. Drone CI server docker image
+
+Use `armhfbuild/drone:0.4` as the Drone CI server image. Should run fine on ARM (like Raspberry Pi 2) and ARM64 (like Estuary D02) docker hosts.
+
+## 2. arm/arm64 rancher/dapper image
+
+Make sure you've done the following before having Drone run RancherOS builds. Run against the same docker daemon you're running Drone with:
+```
+docker pull rancher/dapper:1.10.3_arm
+docker tag rancher/dapper:1.10.3_arm rancher/dapper:1.10.3
+```
+
+This is necessary because `.drone.yml` syntax does not support choosing the image based on the host platform. The actual `rancher/dapper:1.10.3` image on DockerHub is for amd64 (x86_64), so your builds won't run if you don't do that.
