An insuree is able to procure a luggage Insurance Contract for a certain luggage and flight. The InsuranceContractManager created the luggageInsuranceContracts for this use case and manages them. After the flight is executed and the airplane landed there will be a check for a potential claim. In case the luggage is delayed or lost there will be a transfer of the insuranceAmount to the insuree.
This setup requires a working node.js environment.

Truffle provides you with a local blockchain you can use for local development and helpful tools such as compiling your smart contracts, migrating them to your local blockchain and running tests.
Start the local ethereum blockchain with
$truffle develop.
You will see following output:

⚠️ Important ⚠️ : This mnemonic was created for you by Truffle. It is not secure.
Ensure you do not use it on production blockchains, or else you risk losing funds.
You can compile the smart contracts by typing compile inside the truffle developer console.

You can migrate the smart contracts into the local truffle blockchain by typing migrate inside the truffle developer console.
