Summary: An elementary introduction to the non-perturbative renormalization group is presented mainly in the context of statistical mechanics. No prior knowledge of field theory is necessary. The aim of this article is not to give an extensive overview of the subject but rather to focus on conceptual aspects and to explain in detail the main technical steps. It should be taken as an introduction to more advanced readings.
