Instructions:

Get an API key from https://infura.io/dashboard

git clone https://github.com/taarushv/helios.git
cd helios
touch .env // create .env
echo 'INFURA_WS_URL=wss://mainnet.infura.io/ws/v3/alphanumerical_key_from_infura' >> .env // add api key
cat .env // verify the file output
go build && ./helios -client=infura -mode=quick // build and run

Pointing to this issue in the README, thanks for bringing it up @bonevays
