+
+## Prerequisites
+
+Before you begin, ensure you have met the following requirements:
+
+* Node.js >= 10
+
+## Installation
+
+**Download and install Node.js v10.x and npm.**
+
+> Using Ubuntu
+
+```sh
+   $ curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
+   $ sudo apt-get install -y nodejs
+```
+
+> Using Debian, as root
+
+```sh
+   $ curl -sL https://deb.nodesource.com/setup_10.x | bash - 
+   $ apt-get install -y nodejs
+```
+
+**Clone the repo, switch to decagraphics and run npm install**
+
+```sh
+   $ git clone https://gitlab.com/deca-currency/decagraphics.git
+   $ cd decagraphics
+   $ npm install
+```
+
+> It's recommended to fix security vulnerabilities in dependencies using the command.
+
+```sh
+   $ npm audit fix
+```
+
+It is necessary to have installed mongodb locally in case of making a connection to another server modify the connection url of mongodb.
+
+> Once the installation is done, it is necessary to create a database with three collections with the following names:
+```sh
+   $ mongo
+   use DecaGraphics
+   db.createCollection("decaPrice")
+   db.createCollection("decaGeth")
+   db.createCollection("decaCCTS")
+```
+
+> After that it is necessary to set the environment variables in an .env file as in the example .envSample file.
+
+```sh
+   APIKEY=
+   USERDB=
+   PASSDB=
+   DBNAME=
+   INFURAKEY=
+   CONTRACTADDRS=
+```
+
+In both scripts it is necessary to set the variable 'dates' to the following date in unixtime from there the script will start to run the calculations automatically.
+
+**Once everything is configured it is necessary to have ipfs running as a service the configuration can be found in [carboncreditsbacklog](https://gitlab.com/deca-currency/carboncreditsbacklog) as well connecting to the nodes mentioned there in order to replicate the orbitdb carbon credits database bd.**
+
+> The scripts can be tested using node as well the service rest which will take the data from mongodb and expose it in a json format in order to do the calculations on the web page
+
+```sh
+   $ node scriptMainNode.js   
+   $ node index.js
+```
+
+To verify the data can be done from a browser taking into account the use of cors or from a bash.
+
+```sh
+   $ curl localhost:5000/decaPrice
+   $ curl localhost:5000/decaGeth
+   $ curl localhost:5000/decaCCTS 
+```
+
+## Development
+
+* The dependencies are already in the package.json 
+* Ethereum Node 
+* Bitcoinaverage Api
+
+The rest service was made in express.js and cors was applied to accept only requests coming from deca.eco as well as helmet.js was used to give a better security to the application and the good practices of [express](https://expressjs.com/es/advanced/best-practice-security.html).
+
+The main script is scriptMainNode.js performs the calculations found in the document [DECAAnalyticsETHPrice](./pdf/DECAAnalyticsETHPrice.pdf) the other script is backup and is used on another node in case the main one fails.
+
+
+## Deploy
+
+### Prerequisites
+
+* Nginx >= 1.14.0
+* Certbot >= 1.6
+
+Install Nginx 
+
+```sh
+   $ sudo apt update
+   $ sudo apt install nginx
+``` 
+
+Install Certbot
+
+```sh
+   $ sudo add-apt-repository ppa:certbot/certbot
+```
+
+> The script is configured as a service to be able to perform the calculations automatically. The configuration file is located in the service folder.
+
+```sh
+   $ sudo vim /etc/systemd/system/decaGraphics.service 
+   [Unit]
+    Description=Deca Graphics Updater
+
+    [Service]
+    WorkingDirectory=/home/nodemaster/decagraphics/
+    ExecStart=/usr/local/bin/node /home/nodemaster/decagraphics/scriptMainNode.js
+    User=nodemaster
+    Restart=always
+    LimitNOFILE=10240
+
+    [Install]
+    WantedBy=multi-user.target
+```
+
+**NOTE: in this example user that runs ipfs, node and orbitdb instance is nodemaster, also the node location is at /usr/local/bin/node**
+
+**NOTE1: set WorkingDirectory where is the repository, for this example /home/nodemaster/decagraphics/**
+
+**NOTE2: set where is index.js mostly in the repository as follow path to node path, for this example /home/nodemaster/decagraphics/scriptMainNode.js**
+
+> Enable the service
+
+```sh
+ $ sudo systemctl daemon-reload
+ $ sudo systemctl enable decaGraphics.service 
+ $ sudo systemctl start decaGraphics.service 
+ $ sudo systemctl status decaGraphics.service 
+```
+**NOTE: service must be set as active (running), if not please verify the preview steps**
+
+> It is possible to check in the service logs if any error occurred in the service.
+
+```sh
+● graphicsDeca.service - Graphing Calculator
+   Loaded: loaded (/lib/systemd/system/graphicsDeca.service; enabled; vendor preset: enabled)
+   Active: active (running) since Thu 2020-07-23 17:18:50 UTC; 4h 23min ago
+ Main PID: 629182 (node)
+    Tasks: 12 (limit: 464185)
+   CGroup: /system.slice/graphicsDeca.service
+           └─629182 /usr/bin/node /home/nodemaster/decagraphics/scriptMainNode.js

+Jul 23 21:40:02 icowebsrv node[629182]: Insert decaCCTS
+```
+
+Once the service is working properly it is necessary to configure the service subtract to be able to access the data from [deca.eco](https://deca.eco/).
+
+In the nginx config add the proxy pass
+
+
+
+```sh
+$ vim /etc/nginx/conf.d/example.com.conf
+server {
+    listen         80 default_server;
+    listen         [::]:80 default_server;
+    server_name    example.com www.example.com;
+    root           /var/www/example.com;
+    index          index.html;
+    try_files $uri /index.html;
+    location /  {
+        proxy_pass http://localhost:5000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+**Remember to open the port in the firewall**
+
+**Remember to leave the rest service running in a tmux session and check the port.**
+
+**Now restart up Nginx!**
+
+
+### Add SSL Certificate
+
+```sh
+   $ sudo certbot --nginx -d api.deca.eco 
+```
+
+**It is recommended to redirect all http traffic to https**
+
+Finally renew the certificate with the following command and restart nginx
+
+```sh
+$ sudo certbot renew --dry-run
+$ sudo service nginx restart
+```
