-### Configuring the environment (optional)
-
-To have the interface default to a different network when a wallet is not connected:
-
-1. Make a copy of `.env` named `.env.local`
-2. Change `REACT_APP_NETWORK_ID` to `"{YOUR_NETWORK_ID}"`
-3. Change `REACT_APP_NETWORK_URL` to e.g. `"https://{YOUR_NETWORK_ID}.infura.io/v3/{YOUR_INFURA_KEY}"`
-
-Note that the interface only works on testnets where both
-[Uniswap V2](https://uniswap.org/docs/v2/smart-contracts/factory/) and
-[multicall](https://github.com/makerdao/multicall) are deployed.
-The interface will not work on other networks.
