Add a secrets.json at the root directory with the format:

{
  "MNEMONIC": "blah x 12", // your secret phrase from a test https://metamask.io account
  "PROVIDER_URL": "YOUR_INFURA_URL_GOES_HERE" // get yours at https://infura.io
}

Then, you can deploy the test contract to your provider url: node deploy.js

To interact with it on the network, enter your deployed address key on https://remix.ethereum.org

• Go to the Run tab
• Enter your address into the At Address input field

• Web3: js lib to interact with the ethereum network
• Ganache: local-hosted test network; reduces testing latency
• Solc: compiles solidity smart-contracts to bytecode
• truffle-hdwallet-provider: takes a metamask mnemonic
