 ## ARM / Raspberry Pi
 
-Templates for ARM and Raspberry Pi are provided on a best-effort basis. If you can help with maintenance please let the project contributors know.
+It is possible to migrate to use multi-arch templates with OpenFaaS, feel free to ask the community for direction here.
 
-* ARMv7 / Raspberry Pi
-
-Type in `faas-cli new --list` and look for any languages ending in `-armhf`. You can use any of these for your functions.
-
-* ARM64 / Packet.net / Scaleway ARM 64-bit
-
-For these platforms do the same as above and look for the `-arm64` suffix.
-
-> It is easy to make your own templates so if you need to use this platform please convert one of the "regular" templates for your platform.
+Otherwise, for ARM and Raspberry Pi you will need to build on the device, and not on your PC or CI server.
