installation instruction?

installation instruction?

I managed to get jquery UI working somehow but it wasn't easy.
I could not find instruction on how to get jquery UI installed or integrated into my site.

At first I downloaded the development bundle 1.7.2.  I copied out jquery-ui-1.7.2.min.js and put it into my app.  I got one datepicker attached and voila.  It worked but it was also ugly.  I figured out after some searching that I must have not copied some css/images, etc.  This is where he doc is inadequate.

In the downloads, there is no installation document per se.  So it's hard at first to get going.

If you know a place on jquery.com, where this is explained, please let me know.
Thanks
