IMPORTANT NOTE --> Don't use ANY DOT in the usernames, only UNDERSCORE
Following and update an underscore have been set to enable WORKERS NAME.
2. SELECTING THE MINING SOFTWARE
I found GrinProMiner to be the most stable and fastest, But you have multitude others miners to choose from, like Grin Pro, Bminer and so on...
GrinProMiner can be found here
You will need to install dotnet core runtime 2.2 (only on Windows, Linux build is self-contained):
Once .NET installed, extract and start GrinProMiner.exe At first launch it will ask you some questions to configure the miner :
Choose -->  Custom stratum address
END, Miner will start straight away.
I have RX 580’s Nitro+ and I use 1250 @ 875 mV and 2000 @ 875 mV with OverdriveNTool.
You can increase your hashrate by putting 1300 but then my cards would eat too much of electricity to be stable.
If you prefer to choose an other AMD software bear in mind people on BITGRIN DISCORD can help you if you are in trouble.
3. MONITOR FROM THE POOL
For this last one you can withdraw directly to exchange (Vinex,...) using Online Wallet / Port

Open Kingfish wallet wait for full sync (It is not mandatory, but I prefer to do it when I am full sync)
