+===== Software =====
+\\
+This project has the following software components.
+\\
+  - Linux OS for the Raspberry Pi (Raspbian or Noobs)
+  - PHP Libraries      (on the Master Pi only)
+  - Apache Web Server  (on the Master Pi only)
+  - Python
+\\
+The Linux is a specific arm compiled version that runs on the Raspberry Pi. You can run this project in headless mode (no GUI required on the Pi) which helps keep boot times up and resource use down.
+\\
+\\
+The master Pi requires PHP and Apache Web Server, this is just for the hosting of the page that you configure the LCD messages on.
+\\
+\\
+Python is the software that understands the code in the Python script that runs the LCD, this is preinstalled on Raspbian distros.
