+##### Quick Demo
+```
+git clone https://github.com/Salmandabbakuti/IoT-and-Blockchain.git
+cd IoT-and-Blockchain
+npm install
+ganache-cli # local testnet for deployments
+truffle compile 
+pip install -r requirements.txt
+python app.py # Headover to your Computer IP on browser for UI
+
+python appRemote.py # Needs to add your private key inorder to work.
