+# Summary
+
+pyro
+
+In the time since the first pyro paper [@pyroI], the code has
+undergone considerable development, gained a large number of solvers,
+adopted unit testing through pytest and documentation through sphinx,
+and a number of new contributors.  pyro's functionality can now
+be accessed directly through a `Pyro()` class, in addition to the
+original commandline script interface.  This new interface in particular
+allows for easy use within Jupyter notebooks.  
+
+The original goal of pyro was to learn hydrodynamics methods through
+example, and it still serves this goal.  At Stony Brook, pyro is used
+with new undergraduate researchers in our group to introduce them to
+the ideas of computational hydrodynamics.  But the current framework
+has evolved to the point where pyro is used for prototyping
+hydrodynamics solvers before implementing them into science codes.  An
+example of this is the 4th-order compressible solver built on the ideas
+of spectral deferred corrections (the `compressible_sdc` solver).  This
+implementation was used as the model for the development of higher-order
+schemes in the Castro hydrodynamics code [@castro].  The low Mach
+number atmospheric solver (`lm_atm`) is based on the Maestro code [@maestro]
+and the pyro implementation will be used to prototype new low Mach number
+algorithms before porting them to science codes.
+
+The current pyro solvers are:
+
+  * linear advection (including a second-order unsplit CTU scheme, a
+    method-of-lines piecewise linear solver☆, a 4th-order
+    finite-volume scheme☆, and a WENO method☆)
+
+  * compressible hydrodynamics (including a second-order unsplit CTU
+    scheme, a method-of-lines piecewise linear solver☆,
+    and two 4th-order finite-volume schemes, one with Runge-Kutta
+    integration and the other using a spectral deferred corrections method☆)
+
+  * diffusion using a second-order discretization
+
+  * incompressible
+
+  * low Mach number atmospheric solver
+
+  * shallow water equations solver
+
+(solvers since the first pyro paper are marked with a &star).
