+    """PLUMED is an open source library for free energy calculations in
+    molecular systems which works together with some of the most popular
+    molecular dynamics engines.
+
+    Free energy calculations can be performed as a function of many order
+    parameters with a particular focus on biological problems, using state
+    of the art methods such as metadynamics, umbrella sampling and
+    Jarzynski-equation based steered MD.
+
+    The software, written in C++, can be easily interfaced with both fortran
+    and C/C++ codes.
