### Install Node-RED
#### Download and installation
To install Node.js, npm and Node-RED onto a Raspberry Pi, you just need to run the following command. You can review the content of this script [here](https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered).
```sh
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
```
Type `y` at both prompts to accept the installation and its settings.
#### Enable start on boot and launch Node-RED
To run Node-RED when the Pi is turned on or restarted, you need to enable the systemd service by running this command:
```sh
sudo systemctl enable nodered.service
```
You can now start Node-RED by running the following:
```sh
sudo systemctl start nodered.service
```
#### Check the installation
Make sure Node-RED is correctly installed by reaching the following page from the browser of your pi http://localhost:1880 or http://planktoscope.local:1880 from another computer on the same network.
#### Install the necessary nodes
These nodes will be used by the PlanktoScop software and needs to be installed:
```sh
cd ~/.node-red/
npm install node-red-dashboard node-red-contrib-python3-function node-red-contrib-camerapi node-red-contrib-gpsd node-red-contrib-web-worldmap node-red-contrib-interval
sudo systemctl restart nodered.service
```
#### Import the last GUI
From Node-RED gui in your browser, choose the Hamburger menu top right, and then Import. You can paste the code directly from the lastest version of the GUI available [here](https://raw.githubusercontent.com/PlanktonPlanet/PlanktonScope/blob/master/flows/main.json).
You can also download it directly:
```sh
wget -N -O ~/.node-red/flows_planktoscope.json https://raw.githubusercontent.com/PlanktonPlanet/PlanktonScope/master/flows/main.json
sudo systemctl restart nodered.service
```

cd ~/.node-red/
npm install node-red-dashboard node-red-contrib-python3-function node-red-contrib-camerapi node-red-contrib-gpsd node-red-contrib-web-worldmap node-red-contrib-interval
```
We are also going to activate the Projects feature of Node-Red as this will help us manage and track changes to the flows. Open the file `settings.js` with an editor (for example with `nano settings.js`) so we can change the following lines:
```
Line 68: uncomment the line (remove the //) that ends with flowFilePretty: true,
Line 296: set enabled to true
```
Save you changes.
The final step before restarting node-red is to link the projects directory from within node-red folder to our main home directory. To do so, just open a terminal and type the following:
```bash
ln -s /home/pi/.node-red/projects/PlanktonScope /home/pi/PlanktonScope
```
You can now restart the nodered service:
```
sudo systemctl restart nodered.service
```
#### Import the last GUI
If you now open the Node-Red GUI in your browser, it will ask you to setup the project, an email and a username (so if you make changes to the flow and want to share them we can know who made them).
You can now choose to clone an existing repository. Choose a name that makes sense for you, and in the `Git repository URL` field put the main Planktonscope repository: `https://www.github.com/PlanktonPlanet/PlanktonScope.git`.
The latest flow version will be imported immediately.

## Finishing the install
Make sure to update your Pi

This will pull and merge all the changes made since your last update.
### Update node-RED interface
To update the interface and make sure you run the latest version, you need to copy the json config file from the cloned repository to the Node-RED library:
```sh
cp ~/PlanktonScope/flows/main.json ~/.node-red/flows_planktoscope.json
```
