-Sobol' Sensitivity Analyze
-==========================
+Sobol' Sensitivity Analysis
+===========================
+
+This module is used to compute Sobol' indices given model (e.g. simulator or emulator)
+outputs evaluated at chosen Saltelli samples (see the :class:`.Saltelli` class).
+Detailed description of the theory can be found in :cite:t:`Saltelli2002` and :cite:t:`Saltelli2010`.
+The :class:`.SobolAnalyze` class relies on the Python package `SALib` :cite:p:`Herman2017`.
