-(I'm running it on a Raspberry Pi 3 with Raspbian Stretch)
+You can run zenbot on a Raspberry Pi and the default Raspbian OS, but I don't recommend it because mongo has problems with ARM systems as well as 32-bit OSes since it limits the database to 2GB.
 
-**1. Install nodejs.**

+**2. Install docker and docker-compose**
+
+Install docker
+
+`curl -sSL https://get.docker.com | sh`

+
+Reboot, or `sudo systemctl start docker`
+
+Install docker-compose:

-**3. Install this or another mongodb dockerfile made for the rapsberry pi.**
 https://hub.docker.com/r/nonoroazoro/rpi-mongo/
 
-**4.Rename the mongodb dockerfile to "mongo"** so that the conf.js from zenbot works with it.
-In my case:
-`docker tag nonoroazoro/rpi-mongo:latest mongo:latest`
+`docker pull nonoroazoro/rpi-mongo`
+
+**4.Rename the mongodb dockerfile to "mongo"**
 
-**5.Run the mongo dockerfile.**
-`docker run mongo`
-(You can control-c or command-c to close the dialogue after it stays at "waiting for connections on port 27017") 
-`docker ps`
-to make sure mongo is running
+If you use the above image:
 
-**6. Run zenbot.**
-`cd zenbot`
-`docker-compose build`
-`docker-compose up -d`
+`docker tag nonoroazoro/rpi-mongo mongo`
+
+**6. Run zenbot**
+
+```
+cd zenbot
+docker-compose build
+docker-compose up -d
+```
 
 Commands are the same
-`docker run --rm --link zenbot_mongodb_1:mongodb -it zenbot_server ./zenbot.sh [command]`
+
+`docker run --rm --link zenbot_mongodb_1:mongodb -it zenbot_server [command]`
