From http://www.psychstat.missouristate.edu/multibook/mlt08m.html:

>>>When a researcher wishes to include a categorical variable with more than two level in a multiple regression prediction model, additional steps are needed to insure that the results are interpretable. These steps include recoding the categorical variable into a number of separate, dichotomous variables. This recoding is called "dummy coding."<<<

That looks very straightforward.
