# Compiling the Firmware

Compiling the MULTI-Module firmware is not overly difficult, even for a newcomer to embedded code.  All of the configuration options are contained in a single file, which is documented with comments.

At a high level, there are four steps:

**Step 1:**  Download the MULTI-Module source code

**Step 2:**  Install and configure the Arduino IDE tools

**Step 3:**  Edit and compile the code

**Step 4:**  Upload the compiled code to the MULTI-Module

The full documentation for each step can be found on the MULTI-Module GitHub repository:
