 Solver TUI
 ==========
+The PyFluent solver text user interface (TUI) API is provided to command the
+Fluent solver using commands that are Pythonic versions of the TUI commands used
+in the Fluent console.  Much like Fluent's TUI the API provides a hierarchical
+interface to the underlying procedural interface of the program.
+
+The solver TUI API does not support Fluent TUI features such as aliases or
+command abbreviation.  As an alternative, using this API in an interactive
+session is easier if you install a tool such as
+`pyreadline3 <https://github.com/pyreadline3/pyreadline3>`_ which provides
+both command line completion and history.  You can also use Python standard
+`help` and `dir` commands on any object in the API to inspect it further.
+
+The TUI based examples in our gallery provide a guide for how to use this API.

 package for modeling fluid flow, heat transfer, and chemical reactions in
 complex geometries.
 
+Ansys Fluent provides complete mesh flexibility, including the ability to solve
+your flow problems using unstructured meshes that can be generated about complex
+geometries with relative ease. Supported mesh types include 2D
+triangular/quadrilateral, 3D tetrahedral/hexahedral/pyramid/wedge/polyhedral,
+and mixed (hybrid) meshes. Ansys Fluent also enables you to refine or coarsen
+your mesh based on the flow solution.
+
+You can read your mesh into Ansys Fluent, or, for 3D geometries, create your
+mesh using the meshing mode of Fluent. All other operations are performed within
+the solution mode of Fluent, including setting boundary conditions, defining
+fluid properties, executing the solution, refining the mesh, and postprocessing
+and viewing the results.

+Python and Fluent
+-----------------
 Python is a portable, dynamically typed, interpreted programming language that
 is easy to learn, read, and write. It is free to use and distribute and is
 supported by a vast support library of thousands of available packages.
