I've seen BTCpay server but its a bit complicated to me to go into the process of deployment.
I've already seen the Github repo and only choose three processors to go with ( Blockonomics, Savvy, Payscrypt ) as they are the only ones in the list that won't ask for documents and the latter two are not working. So, that only leaves me with "Blockonomics".
so how did you deployed BTCPay Server and can you explain to me what is
