+    """Training of neural networks using backpropagation, resilient
+    backpropagation with (Riedmiller, 1994) or without weight backtracking
+    (Riedmiller and Braun, 1993) or the modified globally convergent version by
+    Anastasiadis et al. (2005). The package allows flexible settings through
+    custom-choice of error and activation function. Furthermore, the calculation of
+    generalized weights (Intrator O & Intrator N, 1993) is implemented."""
