+## Requirements
+
+To get this going you need a working [Docker 18.02.0+ setup](https://docs.docker.com/install/) on an AMD64 or ARM32v7 machine. This includes virtually any PC or a Raspberry Pi 3 or newer. Other ARM boards and some NAS might work too, but have not been tested.
+
+You'll also need [docker-compose](https://docs.docker.com/compose/install/) on your machine.
+
+If you want to controll Zigbee devices you also will need a Zigbee-Stick. Have a look at [Zigbee2MQTT's documentation](https://www.zigbee2mqtt.io/getting_started/what_do_i_need.html) for that.
 
 ## Containers
-Uses mqtt, node-red and zigbee2mqtt
+Uses [Eclipse Mosquitto](https://hub.docker.com/_/eclipse-mosquitto), a custom built Node-Red container and [zigbee2mqtt](https://github.com/Koenkk/zigbee2mqtt.io)
 
 ## Getting started
 * Install docker and docker-compose

 ## Manual start
 * run `./start.sh data` to create the necessary folders
-* On a AMD64-System use `docker-compose -f up -d`
-* On a Raspberry Pi/ARM-based systems use `docker-compose -f docker-compose.yml -f docker-compose.arm.yml up -d`
-* If you do not want to start zigbee2mqtt, add the name of the nodered-container: `docker-compose -f docker-compose.yml -f docker-compose.arm.yml up -d nodered`
+* Use `docker-compose up -d` to start the containers
+* If you do not want to start zigbee2mqtt, add the name of the nodered-container: `docker-compose up -d nodered`. The mqtt container will always be started, because it's a dependency of Node-Red.
