Working with Curve Source Repo, Including running from Brownie.

For starters, there is a pdf manual for brownie that should be found and utilized.

The way to configure the infura or whatever provider is via the command line,
in there you will want to set your mnemonic as well as your infura key or private RPC

$ brownie networks list true
$ brownie networks modify mainnet-fork mnemonic="\"your twelve word mnemonic\""
$ brownie networks modify mainnet host=https://rinkeby.infura.io/v3/dklfjh0g8og8ohg845jhsgr98
