x and y labels in ArrayPlot

I would like to plot an array of integer values, and to put labels on 
each row (a,c,b) and column (A,B,C) of the array, with x-labels on the 
left and y-labels above and potentially rotated by 45 or 90 degrees. 
ArrayPlot seems appropriate, but I do not see how to add the labels. 
I've tried to check the Help documentation carefully, including 
MatrixPlot and alternatives, and the WRI demonstrations.

data = {{1, 2, 3},
   {2, 3, 4},
   {3, 4, 5}}
yLabels = {"a", "b", "c"}
xLabels = {"A", "B", "C"}

Thanks for your help.
