# Introduction

In this portion of Formulaic's documentation, we introduce the high-level
concepts behind formulas, where they are useful, and how to use the
implementation of formulas provided by `formulaic`

.

If you are unfamiliar with formulas, a brief introduction is provided in the What are formulas? section. If you are already familiar, you can skip forward to the Formula Grammar and User Guides.

For a more detailed description of how Formulaic parses and materializes formulas, as well as how to augment and/or control this behavior, please refer to the Advanced Usage sections.
