 ## How to mine on P2Pool
 
 This guide assumes that you run everything on the same machine. If it's not the case, change `127.0.0.1` to appropriate IP addresses for your setup. It's highly recommended to create a new mainnet wallet for mining because **wallet addresses are public on p2pool**.

 - Check that ports 18080 (Monero p2p port) and 37889 (p2pool p2p port) are open in your firewall to ensure better connectivity
-- Use the `monerod` binary bundled with p2pool (official binaries don't have p2pool support yet)

 - Run `./monerod --zmq-pub tcp://127.0.0.1:18083 --disable-dns-checkpoints --enable-dns-blocklist` **don't forget --zmq-pub parameter in the command line**
