About "npm run start"

[ozgurk78]

Hello

How should I run the part below?

For example, should I type the Private Key on the command line? Or should I write it in Index.js?

$ PRIVATE_KEY=PRIVATE_KEY_FROM_ABOVE
BUNDLE_EXECUTOR_ADDRESS=DEPLOYED_ADDRESS_FROM_ABOVE
FLASHBOTS_RELAY_SIGNING_KEY=RANDOM_ETHEREUM_PRIVATE_KEY
npm run start

You should run the commands in the terminal, then run 'npm run start'

You can use "dotenv" which allows us to use configuration files
