What is the mining command? How to operate it?
You can unzip and run the miner without any arguments - it'll mine to your node's wallet.
You can also mine to your web wallet - you'll need the legacy address from the wallet page -
example
repnet-miner.exe --address=1P7ydDvdUoJf7hFLa3SrBD8tGfUaZaT1Ts
