This guide will show you how to download from The Pirate Bay.
Click "download this torrent": here's a screenshot.
Choose a folder to download the files to (picture 1).
Now it should look something like picture 2. The info speaks for itself, but some of it will change after a while as you get connected to more seeds and peers.
The icon on your far left will be green when you are connected to seeds and there's no problems with firewalls or stuff like that. If it's yellow you might need to configure your firewall, but the download should work just fine anyway. If the icon is red, it means that you are not connected to anyone having 100 % of the file. The torrent might be dead or the uploader might be away. Patience is your friend.
You can set the upload limits as on picture 2. The better upload, the better download.
You can see how many percents you have downloaded in the titlebar (in this case 5.0 %). If you get an tracker error, wait a while or just try again later.
Always try to upload at least as much as you download. Thats the way to keep the bittorrent network alive. On picture 2 you see the "Share rating": having a share rating above 1.0 means you have uploaded more than you have downloaded, which is good. In this case 0.000, which is bad. But when you have 100 %, just wait and more peers might connect. If there hasn't been any new peers for a few days, you may disconnect even though your rating is bad.
If you need to shut down your computer, you have to open the torrent again and save to the exact same place for resuming.
