 - **gulp debug**: builds the bundle `/dist/synaptic.js` with sourcemaps.
 - **gulp dev**: same as `gulp debug`, but watches the source files and rebuilds when any change is detected.
 - **gulp test**: runs all the tests.

+********************************************************************************************
+
+Synaptic is a javascript neural network library for node.js and the browser, its generalized
+algorithm is architecture-free, so you can build and train basically any type of first order
+or even second order neural network architectures.
+
+http://en.wikipedia.org/wiki/Recurrent_neural_network#Second_Order_Recurrent_Neural_Network
+
+The library includes a few built-in architectures like multilayer perceptrons, multilayer
+long-short term memory networks (LSTM) or liquid state machines, and a trainer capable of
+training any given network, and includes built-in training tasks/tests like solving an XOR,
+passing a Distracted Sequence Recall test or an Embeded Reber Grammar test.
+
+The algorithm implemented by this library has been taken from Derek D. Monner's paper:
+
+A generalized LSTM-like training algorithm for second-order recurrent neural networks
+http://www.overcomplete.net/papers/nn2012.pdf
+
+There are references to the equations in that paper commented through the source code.
