@@ -7,7 +7,7 @@ LaMEM (Lithosphere and Mantle Evolution Model) is a parallel 3D numerical code t
 geodynamical processes such as mantle-lithosphere interaction for rocks 
 that have visco-elasto-plastic rheologies. It was developed to better understand geological 
 processes, particularly related to the dynamics of the crust and lithosphere and their 
-interaction with the mantle. It can also be used to solve geomechanical problems, includes (compressible) poroelasticity, has a gravity solver and an (adjoint) inversion framework. The code uses a marker-in-cell approach with a staggered finite difference discretization and is build on top of [PETSc](https://petsc.org) such that it can run on anything from a laptop to a massively parallel machine.

 A range of (Galerkin) multigrid and iterative solvers are 
 available, for both linear and non-linear rheologies, using Picard and
