 MeshPy offers quality triangular and tetrahedral mesh generation for Python.
-Meshes of this type are chiefly used in finite-element simulation codes, but
+Meshes of this type are mainly used in finite-element simulation codes, but
 also have many other applications ranging from computer graphics to robotics.
 
 In order to generate 2D and 3D meshes, MeshPy provides Python interfaces to
