Without getting too technical, an ARM (or Advanced RISC Machine) usually refers to a very small and usually cheap device that is often created for a very specific task. These machines are so called because they use an ARM processor (a small processor with less speed/capabilities than a traditional computer processor). You often see these processors in small devices like cellphones, watches, or othes that have a limited amount of space and/or battery power.
In the context of Ignition, you might take a small device (like a Raspberry Pi or similar) and install Ignition to create an edge of network device for simple data logging. You could also install a slimmed down operating system like Linux and use the device as a client for an existing Ignition installation. This page details installing Ignition on the device and is focused on our edge of network example rather than using the device as a client.

ARM Processor Installation
Installing Ignition on an ARM processor cannot be done with the standard installation executable, but is otherwise very simple. To install on ARM, follow these steps:
The zip will also contain a README file that will contain some useful information on the installation process.
On the Ignition Downloads page, scroll down to the ARM section of the zip files.
There is a separate ARM installer file for Ignition Edge named Ignition-Edge-linux-armhf-x.x.x.zip.
Download the appropriate zip file (Ignition-Linux-armhf-x.x.x.zip) using the download link. Note: Depending on your computer, you may need to run all the commands as root. Prefix everything with sudo or first run sudo su.
Unzip the Ignition download file into /usr/local/ignition by running the following command:
