Hello, there is docker image on that link that could be helpful.
Also have a Synology (DS 716 II) and started playing around, but had issues once I installed Virtual Machine Manager.
So I followed the Poapool guide instead to install a HTN Node, then BigPey made a Youtube video on how to connect your HTN node to Mainnet (Friends & Family pool).
There will be issues, that’s what Telegram groups are for, to help you.
You just have to follow the instructions!
