The website of the Embassy in Algiers contains all the general information you need. See also the answer to this similar question.
The details on the process as well as the documents you need depend on the visa type, the reason for the refusal, and especially on what point of the refusal you want to contest and why. An appeal only makes sense if the decision is incorrect and unjust, it is not a way to "give it a second try".
