+Meshmode provides the "boring bits" of high-order unstructured discretization,
+for simplices (triangles, tetrahedra) and tensor products (quads, hexahedra).
+Features:
 
-.. TODO
+- 1/2/3D, line/surface/volume discretizations in each, curvilinear supported.
+- "Everything is a (separate) discretization." (mesh boundaries are, element surfaces are,
+  refined versions of the same mesh are) "Connections" transfer information
+  between discretizations.
+- Periodic connectivity.
+- Mesh partitioning (not just) for distributed execution (e.g. via MPI).
+- Interpolatory, quadrature (overintegration), and modal element-local discretizations.
+- Independent of execution environment (GPU/CPU, numpy, ...)
+  via `array contexts <https://github.com/inducer/arraycontext/>`__.
+- Simple mesh refinement (via bisection). Adjacency currently only
+  maintained if conforming.
+- Input from Gmsh, Visualization to Vtk (both high-order curvilinear).
+- Easy data exchange with `Firedrake <https://www.firedrakeproject.org/>`__.
+
+Meshmode emerged as the shared discretization layer for `pytential
+<https://github.com/inducer/pytential/>`__ (layer potentials) and `grudge
+<https://github.com/inducer/grudge>`__ (discontinuous Galerkin).
