hi @Parlocameon
ACME-Sharp is a PowerShell Library which means you do need to be familiar with PowerShell to get the most out of it
If you are trying to use Let's Encrypt on windows and are not comfortable to a medium level with powershell I would suggest using one of the other clients (your time is probably better spent learning those)
letsencrypt-winsimple
Certify
