The time I learned it I used the Wikipedia article, apparently it wasn't that bad that time I used it (haven't checked now). But it needs some hand-crafting to get into it. In principle, if you decompose the operation of Quaternions manually (which involves a bit of algebra, but doable), then you'll see how beautifully it decomposes the vector given in to create a local rotation plane, where it is rotated just as in ordinary polar coordinates.
