Set-up tips?

[webspacecreations]

Set-up instructions conflict b/w repository README and package.json. Would someone who has successfully configured this (for testnet or mainnet) kindly share what needs to be updated?
#1. Replace private key in .env file
#2. In constants.js, ACCOUNT=<'proton address'>, ACCOUNT_PERMISSION=<?>, and CHAIN=<'proton'/anything else> for mainnet/testnet
#3. For mainnet, it appears that "-test" and "testnet" need to be removed from settings.json, but it's not mentioned anywhere. Is that correct?

Anything else? It appears the documented testnet XPR faucet at https://monitor.testnet.protonchain.com/ is broken or out of tokens, but I haven't used this before and a confirmation would be helpful. Overall this looks like a useful repository if I can get past these initial configuration hurdles.
