+     <strong>Fast field line tracing for spherical vector fields</strong>
+   </p>
 
-Python extension for tracing field lines using the
-`MapFL <https://github.com/predsci/MapFL>`_ Fortran tracer.
+
+**mapflpy** is a python package for tracing field lines using the
+`MapFL <https://github.com/predsci/MapFL>`_ Fortran tracer developed by
+Predictive Science Inc.
 
 The goal of **mapflpy** is to provide fast and accurate tracing capabilities for
 spherical vector fields inside a convenient Python interface. **mapflpy** is
-designed to work natively with the staggered meshes produced by
-Predictive Science Inc.'s codes for simulating the solar corona, and 
-inner heliosphere (*e.g.* `MAS <https://www.predsci.com/mas>`_ or
-`POT3D <https://github.com/predsci/POT3D>`_), but it should be generally compatible
-with any global vector field that can be described on a rectilinear grid in 
-spherical coordinates.
