+Mathematical Components is the name of a library of formalized
+mathematics for the Coq proof assistants. It covers a variety of
+topics, from the theory of basic data structures (e.g., numbers,
+lists, finite sets) to more advanced results in various flavors of
+algebra. This library constitutes the infrastructure for the machine
 checked proofs of the Four Color Theorem and of the Odd Order Theorem.

-The reason of existence of this book is to break down the barriers to entry.
-While there are several books around covering the usage of the Coq system and
-the theory it is based on, the Mathematical Components library is built in an
-unconventional way. As a consequence this book provides a non standard
-presentation of Coq, putting upfront the formalization choices and the proof
-style that are the pillars of the library.
+This book aims at providing an introducing to the design patterns used
+throughout this library, so as to ease its use for other projects.
+While there are several books around covering the usage of the Coq
+system and the theory it is based on, the Mathematical Components
+library uses a few design patterns that differ from the methodology
+propose in other sources. As a consequence, this book provides a
+slightly non-standard presentation of Coq, putting upfront the
+formalization choices and the proof style that are the pillars of the

-This books targets two classes of public. On one hand newcomers, even the more
-mathematical inclined ones, find a soft introduction to the programming
-language of Coq, <em>Gallina</em>, and the <em>Ssreflect</em> proof language.
-On the other hand accustomed Coq users find a substantial account of the
-formalization style that made the Mathematical Components library possible.
