+#Introduction
+
+The Gudhi library is an open source library for Computational Topology and
+Topological Data Analysis (TDA). It offers state-of-the-art algorithms
+to construct various types of simplicial complexes, data structures to
+represent them, and algorithms to compute geometric approximations of shapes
+and persistent homology.
+
+The GUDHI library offers the following interoperable modules:
+* Complexes:
+   * Cubical
+   * Simplicial: Rips, Witness, Alpha and Čech complexes
+   * Cover: Nerve and Graph induced complexes
+* Data structures and basic operations:
+   * Simplex tree, Skeleton blockers and Toplex map
+   * Construction, update, filtration and simplification
+* Topological descriptors computation
+* Manifold reconstruction
+* Topological descriptors tools:
+   * Bottleneck distance
+   * Statistical tools
+   * Persistence diagram and barcode
+
+For more information about Topological Data Analysis and its workflow, please
+refer to the [Wikipedia TDA dedicated page][1].
