Pruning Azaleas

Every web site I look at tells me when to prune an azalea but none tells me exactly how to prune one. I find that it is not obvious where to cut. does anyone know of a web site that has pictures showing this. I failed to prune my indoor plant after it flowered apart from pulling off the dead petals. As a consequence it now has large brown bulbous knots at the tips and I cant see any new green growth. Shall I prune now even though all the books say not?

 

Not an azalea expert but I think the brown knots could contain next years flower buds, so pruning off these would be detrimental to next years flowers...anyone confirm this?

 

Thanks Marley - the second site is excellent and has answered my question - I've most likely pulled off the new growth!!
