-# This documents how to run the server on a Raspberry PI (3B)
+# Server documentation

+For simple use and installation, the server services are empacted into a docker-compose. There will be containers for:
+- mosquitto (MQTT broker)
+- Nodered (No code web based programming tool)
+
+> The first 2 steps can be skipped if you're using an other server and dont need to install raspbian and docker. (You'll only need docker, docker-compose ) 
 
 ## Install raspbian on the PI
 We need to install a linux on the PI.
 
 Download the Raspberry PI Imager on [https://www.raspberrypi.com/software/](https://www.raspberrypi.com/software/)
 
-or on Ubuntu with :

+- Select the base raspbian image or similar (needs to be debian based for the exact commands to work)
+- Select your SD card
+- Configure Wifi and ssh for simpler use (Click on the bot right gear)
