+    """
+    The Dakota toolkit provides a flexible, extensible interface between analysis codes and iterative systems
+    analysis methods. Dakota contains algorithms for:
+
+    - optimization with gradient and non gradient-based methods;
+    - uncertainty quantification with sampling, reliability, stochastic expansion, and epistemic methods;
+    - parameter estimation with nonlinear least squares methods;
+    - sensitivity/variance analysis with design of experiments and parameter study methods.
+
+    These capabilities may be used on their own or as components within advanced strategies such as hybrid optimization,
+    surrogate-based optimization, mixed integer nonlinear programming, or optimization under uncertainty.
