CCL: Monte Carlo techniques Tutorial

Dear CCLers,

I am looking for a tutorial (or a code with the tutorial)
that explains monte carlo techniques
for a chemist, who wanted to perform some simulation on thin film deposition
based on the parameters obtained from DFT. 

I am a beginner and wanted to move from DFT to such analytical methods,
as i find it difficult to address the large scale problem using these expensive methods.

Therefore any help or your suggestions would be appreciated.
