Welcome to FeedMe! This tutorial will help you get set up.
You can install FeedMe on as many machines as you would like, and use the same username and password on all of them. If you are installing FeedMe for the first time, go through each step of the tutorial.
If you are installing FeedMe on a second (or third!) machine, you will only have to go through the Firefox, Greasemonkey, FeedMe, and FeedMe bookmarklet installations, and will have to login the first time you load Google Reader on the new machine.
When you are ready to begin the tutorial, you may proceed to the next step.
