Doubleclick the file you downloaded and Bittorrent will install, you will get a message that Bittorrent
  has been succesfully installed. There are no setup menus, shortcuts, links in your start menu and so
  on. There only is a folder in your program files folder on your pc called Bittorrent.
  (or whatever the client of your choice is called) which holds the program, start it from there. Note that
  some clients do install a desktop/start menu shortcut.
  Normally your client will start automatically when you open a .torrent file from your
  harddrive or from a website server.

  Now go to one of the sites below and click the link of the file you want. Download the .torrent file to
  your pc and open it from there or open it from the site you wanna download from.
  Make sure that you pick a file that is seeded (see below). Select a placeon your harddrive where
  you want to download  the file to and click save. The Bittorrent window will now pop up (depending
  on your client) and soon your download will start. First Bittorrent will allocate enough space on your
  hard disk for the file you want to download, this can take a couple of minutes and ofcourse
  make sure you have enough hard disk space. When finished allocating, your client will try to connect
  to the tracker. You might see some errors, most you can ignore, only worry if you havent started
  downloading after 20 minutes or so and you still get errors. Then just close your client and restart it
  and then restart and resume the download.
 

Soon after your download starts, you will also start to upload the pieces you have downloaded to others. When you finish
downloading keep your Bittorrent window open for a couple of hours to help upload the file to other users. Uploading a file is called 'seeding' and downloading and uploading the part you have downloaded is called 'leaching'. If there are no seeders for a torrent, you can't get the complete file.

Ignore the errors: failed to connect to tracker and timed out and so on, only worry if your download doesn't start or stops when it's not supposed to. 

On some sites when you click a link you will be asked: Download file: open from current location or save this file to disk. Select open from current location to open the .torrent file and start the download or select save this file to disk to save the .torrent file to your pc. You can open it there (from your pc) to start the download or check with Torrentspy if the file is being seeded or save the .torrent file for later use.

On most sites you can see how many people are seeding and leaching a file, make sure the file you want has at least 1 seeder/complete or you won't be able to get the complete file. The ratio seeders:leechers is somewhat important for your download speed. Rule usually is, many seeders means that you'll finish your download faster. If there are a few seeders and lots of leechers, your speed will be average. More seeders than leechers means that your download speed will go to the max!!

Usually when you download something with Bittorrent, you get the complete file (complete .avi or .mpg file). Sometimes you'll get a whole buch of files which are  about 15 Mb per file, usually in 2 or 3 separate folders, with filenames like .r01 and .r02 or something alike. These are WinRar files. You get these files often when you download a really new movie (usually screeners) or game. Other times you may get a .cue and a .bin file. These are image files made by a cdr-burning program like Nero or CDRWin.

Rar files

To extract all the .rar files (.r01 and so on) you downloaded, you'll need WinRar.  Get WinRar on http://www.rarlab.com/download.htm or from Bittorrent or Kazaalite or another p2p program or source and install it.

First find a file you want to make a torrent of. Put that file in a separate folder on your hard disk, all the files in that folder will be included in the torrent.

Download the completedir for windows from http://bitconjurer.org/BitTorrent/download.html, and install it. (Or use the one that's on the Burst! site: http://krypt.dyndns.org:81/torrent/, this 'how to' is for the bitconjurer.org one). Same deal as bittorrent, no links, no shortcuts. In your program files folder you will find a folder called: completedir. In this folder is the file btcompletedirgui.exe, open this.

Announce url: type the announce url you want to use (http://bittorrent.bounceme.net and http://www.torrentse.cx have good public trackers which anyone can use. The tracker will guide the up and downloading of your torrent to other bittorrent users. Visit the upload sections of bittorrent.bounceme.net, or http://www.torrentse.cx/ for the current announce url. It's pretty easy. Make sure you include the /announce part of the link, more tracker sites are on my mainpage, they are marked (tracker).

Leave the piece size as it is.

Hit 'make' and completedir will make the torrent file of the file you want to seed. After completedir is finished click 'close' and close down completedir. The .torrent file will be in the same folder as the file you made the torrent of.

Now go to the site you use as a tracker for your torrent and upload your .torrent file (i.e. if you use bounceme.net, upload your .torrent file there).

Now open the torrent file you made from your hard drive or open it from the website you uploaded it to. Save the file (save the real file, not the .torrent file) to the folder on your hard disk which holds the file you want to seed. Bittorrent will now check the existing file on your hard disk and if all's well, at the end it will say 'finished' and other people can begin to download the torrent from you. Make sure you leave the bitTorrent download window open long enough so at least a couple of people can download the complete file from you so they can help seed or take over seeding.
