+## Requirements:
+```
+This script is made for and tested on Raspberry Pi 4's with at least 2GB of RAM.
+The OS used and tested on is: Raspberry Pi OS Lite x64 version 11 / Bullseye.
+An official Raspberry Pi power supply.
+A good SD card with 16GB storage or more (read the FAQ: Just use any SD card?) for more information.
+
+Optional:
+Zigbee Dongle CC2531/CC2652P.
+LAN cable.
+
+Best to worst Pi's to use that are supported by this installer:
+Pi 4 2GB / 4GB / 8GB
+Pi 4 1GB (mounting /tmp to RAM will be disabled)
+Pi 3B+ (may lack the power and/or resources to run all the installer options, also mounting /tmp to RAM will be disabled)
+Pi 3B (may lack the power and/or resources to run all the installer options, also mounting /tmp to RAM will be disabled)
+
+Why more then 1GB of RAM? Read the FAQ: 1GB of RAM not good enough? for more information.
