# ARM - Install

> 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.

## What is ARM?
Without getting too technical, an **ARM** (or **A**dvanced **R**ISC **M**achine) 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.

## 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:

:::note
The zip will also contain a README file that will contain some useful information on the installation process.
:::

1. Go to the Inductive Automation website at www.inductiveautomation.com
2. Select **Download > Current Release**.
3. 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.**
4. 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`.
    :::
5. Download and install Java 8 if it is not already installed. Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html
6. Unzip the Ignition download file and install Ignition into `/usr/local/ignition` by running the following command:
    ```
    unzip <<ignition-Linux-armhf-x.x.x.zip>> -d /usr/local/ignition
    ```
    
    where `<<ignition-Linux-armhf-x.x.x.zip>>` is the path to the Ignition ARM distribution you downloaded.
 
7. Change directories to the Ignition install directory.
    ```
    cd /usr/local/ignition
    ```
8. Make the files executable by executing the following three chmod commands:
    ```
    chmod +x ignition.sh
    chmod +x ignition-gateway
    chmod +x gcu.sh
    ```
9. To start Ignition now, type `./ignition.sh start`

You can now open a web browser and go to the Gateway home page at http://localhost:8088.

### Stop and Start Ignition
After installation, you can start and stop Ignition with the following commands:
```
./ignition.sh start
./ignition.sh stop
```
