I did all the steps for the masternode, it says successfully started in the console, however I have a question. in the desire path there is a file named masternode.conf, inside the file, you need to add any line there?
It looks kinda like this:

# Masternode config file
# Format: alias IP:port masternodeprivkey collateral_output_txid collateral_output_index
# Example: mn1 127.0.0.2:19919 93HaYBVUCYjEMeeH1Y4sBGLALQZE1Yc1EDSeo435SDso34

Can anyone explain please?
