Eric Sims at Notre Dame has an excellent set of self contained notes:
http://www3.nd.edu/~esims1/using_dynare_sp15.pdfself contained notes.
He uses a small neoclassical model as an example and goes over the model derivation, how to construct each block of Dynare code, different simulation options, interpreting output, and how to do higher order approximations. Full code is included for each step in the notes.
