+
+This guide is going to install Node-RED on an edge device using [balena.io](https://balena.io) in 1 click. Running Node-RED on balena, means that you are using containers and Node-RED can run alognside with other services such as MQTT, databases, LoRa Network Servers and more. balena is a platform for managing fleets of connected devices. 
+
+
+### Hardware required
+
+To build this project, you will need:
+
+* Raspberry Pi 0, 2, 3, 4 or [balenaFin](https://www.balena.io/fin/)
+* An SD card if you are using a Raspberry Pi
+* Power supply and (optionally) Ethernet cable.
+
+
+### Software setp
+
+To set up this project, you'll need:
+
+* a [balenaCloud account](https://dashboard.balena-cloud.com/) (remember that the first 10 devices are fully-featured and free)
+* [balenaEtcher](https://www.balena.io/etcher/) to flash the SD card.
+
+
+
+## Tutorial
+
+### Deploy Node-RED in 1 click
+
+The Node-RED application with [balena-supervisor](https://balena.io/docs/reference/supervisor/supervisor-api/) flow [support](https://github.com/balena-io-projects/node-red-contrib-balena), can be managed remotely via balena [publicURL](https://balena.io/docs/learn/manage/actions/#enable-public-device-url).
+
+You can deploy this project to a new balenaCloud fleet in one click using the button below:
+
+[![](https://balena.io/deploy.svg)](https://dashboard.balena-cloud.com/deploy?repoUrl=https://github.com/balenalabs/balena-node-red)
+
+Clicking the deploy button will create an application with all the necessary code to deploy your Node-RED project.

+
+<img src="images/balena-device-nodeRED.png" />
+
+Once the `Node-RED` service has been deployed on your device, copy your local IP (if you are using the same network) or just click on `Public Device URL` and access to the Node-RED UI.
+
+To access to the Node-RED UI, use `balena` as username and password. You may want to modify the `USERNAME` and `PASSWORD` on the balenaCloud Device Variables.
+
+Now you are ready to start using Node-RED on your device.
+
+
+### Deploy Node-RED from balena CLI
+
+The previous application was running Node-RED however if you would like to run more services alongisde on the same device, this is also possible.
+
+You will need to have installed on your computer the [git CLI](https://github.com/git-guides/install-git) and the [balena CLI](https://www.balena.io/docs/reference/balena-cli/).
+
+First thing you need to do is to clone the [balena Node-RED block](https://github.com/balenalabs/balena-node-red).
+
+````
+cd ~/workspace
+mkdir balena-node-red-mqtt
+cd balena-node-red-mqtt
+git clone https://github.com/balenalabs/balena-node-red.git
+```
+
+#### Add MQTT mosquitto service 
+
+Let's add to the Node-RED service on balena another service. In this example we are going to add the MQTT mosquitto service.
+
+Create a `docker-compose.yml` file and add this:
+
+````
+version: '2'
+
+volumes:
+    data:
+    database:
+
+services:
+  node-red:
+    build: ./balena-node-red
+    volumes:
+      - 'data:/data'
+    restart: always
+    privileged: true
+    network_mode: host
+    labels:
+      io.balena.features.supervisor-api: '1'
+      io.balena.features.balena-api: '1' 
+    environment:
+      - "USERNAME=balena"
+      - "PASSWORD=balena"
+      - "ENCRIPTION_KEY=balena"
+    cap_add:
+      - SYS_RAWIO
+    devices:
+      - "/dev/mem:/dev/mem"
+      - "/dev/gpiomem:/dev/gpiomem"
+      - "/dev/i2c-1:/dev/i2c-1"
+    ports:
+      - 80:80
+
+  mqtt:
+    image: arm32v6/eclipse-mosquitto
+    network_mode: host
+    ports:
+      - "1883:1883"
+    restart: always
+```
+
+#### Deploy the Node-RED and MQTT with balena CLI
+
+* Sign up on your balena.io account.
+* Create a new fleet on balenaCloud.
+* Add a new device and download the image of the balenaOS that the balenaCloud creates. Remember to introduce your WiFi credentials, in case you are going to use WiFi.
+* Burn an SD card (if you are using the Raspberry Pi) using balenaEtcher.
+* Once the flashing process has completed, insert your SD card into the device and power it up.
+
+When the device boots for the first time, it connects to your network automatically and then appears to the balenaCloud dashboard. After a few moments, you will see the new provisioned device listed and online.
+
+Now using the balena CLI, push the code to your fleet using `balena push <the-name-of-your-fleet>`. And see the magic happening, your device is getting updated over-the-air.
+
+Once the project has been built on the balena builders, you should see your device downloading the new images containers and starting them.

+In this repository you can find an example of [nodeRED and MQTT mosquitto](https://github.com/mpous/balena-nodered-mqtt) on balena.
