+# Cloud Carbon Footprint
+
+## Prepare Azure
+
+Create an App registration, add a new client secret and save the following information:
+
+- Application (client) ID => AZURE_CLIENT_ID
+- Directory (tenant) ID => AZURE_TENANT_ID
+- client secret value (not Secret ID) => AZURE_CLIENT_SECRET
+
+Give this app registration rights in the subscriptions you want to track and add the following roles:
+
+- Reader
+- Billing Reader
+- Carbon Optimization Reader
+
+Install a VM in Azure and SSH to the machine e.g. using a private key:
+
+``` sh
+chmod 400 ~/.ssh/ccfkey.pem
+ssh -i ~/.ssh/ccfkey.pem carbonuser@1.1.1.1
+```
+
+## Install dependencies
+
+``` sh
+sudo apt install iptables-persistent nodejs
+nvm install --lts
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
+export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" 
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
+nvm install --lts
+corepack enable yarn
+```
+
+Check installed versions
+
+``` sh
+nvm --version
+yarn --version
+node --version
+npm --version
+```
+
+## Install CCF
+
+### Download
+
+Download and unzip the latest release
+
+``` sh
+wget https://github.com/cloud-carbon-footprint/cloud-carbon-footprint/archive/refs/tags/latest.tar.gz
+tar -xzvf latest.tar.gz
+cd cloud-carbon-footprint-latest
+```
+
+### Config .env
+
+Go to cloud-carbon-footprint folder and update the .env file
+
+``` sh
+sudo nano ~/cloud-carbon-footprint-latest/packages/api/.env
+```
+
+with the following content (e.g. for azure)
+
+``` txt
+# Azure
+AZURE_USE_BILLING_DATA=true
+AZURE_INCLUDE_ESTIMATES=true
+AZURE_CLIENT_ID=<add here>
+AZURE_CLIENT_SECRET=<add here>
+AZURE_TENANT_ID=<add here>
+AZURE_AUTH_MODE=default
+AZURE_CONSUMPTION_CHUNKS_DAYS=0
+AZURE_SUBSCRIPTION_CHUNKS=0
+```
+
+do the same for:
+
+``` sh
+sudo nano ~/cloud-carbon-footprint-latest/packages/cli/.env
+```
+
+Use the `.env.template` as orientation for required variables.
+
+### Install and run
+
+Install and run cloud carbon footprint
+
+``` sh
+cd ~/cloud-carbon-footprint-latest
+yarn install
+```
+
+You need to terminals.
+
+Run this in the first terminal:
+
+``` sh
+cd ~/cloud-carbon-footprint-latest
+npm run start-api
+```
+
+and this in the second terminal:
+
+``` sh
+cd ~/cloud-carbon-footprint-latest
+yarn start
+```
+
+The application should now run and be available on Port 3000. Open the URL (e.g. localhost:3000 or your-ip:3000) and check both terminals to see if there are any errors. The first run should take a while and required some refreshes on the web interface for me to start triggering the API to call and deliver data.
+
+## Optimize
+
+### Redirect to Port 80
+
+Redirect port 3000 to standard http port 80.
+
+``` sh
+sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000
+sudo netfilter-persistent save
+```
+
+### Configure nginx
+
+TODO
+
+### Enable HTTPS
+
+TODO
+
+``` sh
+sudo apt install certbot python3-certbot-nginx
+sudo certbot --nginx
+sudo certbot renew --dry-run
+```
+
+### Autostart
+
+TODO
+
+To automatically start cloud-carbon-footprint do the following:
+
+``` sh
+sudo nano /etc/systemd/system/cloud-carbon-footprint-api.service
+```
+
+And add this content
+
+``` sh
+#!/bin/bash
+# Load nvm so that the proper Node version is available
+export NVM_DIR="/home/youruser/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
+cd cloud-carbon-footprint-latest
+npm run start-api
+```
