Step One: Get a VPN. I use PIA and have a 3 year subscription with them because it was what was cheapest when I was choosing, but there are plenty other options you can go with.
Whether or not you absolutely need a VPN will depend on your ISP and your country's laws, but usually people do recommend you have one just to be on the safe side. In some countries I've been able to pirate things without a VPN with no issue, in other countries I've had to use a VPN for every step of the piracy process just to even be able to access piracy related sites.
Step Two: Get a torrent client. I use qBittorrent because it's open source and has no ads, but there are plenty of other options you can go with. I would however recommend avoiding µTorrent.
