+Trajectory Optimization
+=======================
+
+In `pykep` both direct and indirect optimization techniques are provided
+to perform spacecraft trajectory optimization. Most direct techniques provided are
+based on the "Sims" transcription :cite:p:`sims`, while indirect techniques are based on some
+version of Pontryagin Maximum Principle.
+
+Most of the classes in this Trajectory Optimization module are provided as
+optimization problems (NLP) compatible to the pagmo software suite.
