First step setting up your project: 
1. `brownie init`
       
    or use [chainlink-mix](https://github.com/smartcontractkit/chainlink-mix).
   
2. `brownie bake chainlink-mix & mv chainlink (project_name)`

Create `dot.env` file inside your project's directory and include the following:
    `export PRIVATE_KEY_1 = PRIVATE_KEY_1`
    `export WEB3_INFURA_PROJECT_ID = PROJECT_ID`
    `export ETHERSCAN_TOKEN = API_TOKEN`

In order to encrypt your private key, add it to Brownie:
    `brownie accounts new <account_id>`

  `brownie compile`

  `brownie test --network <choose_network> -s`

  `brownie run scripts/deploy_lottery.py --network <choose_network>`
