 Writing a problem module can be extremely complicated, but for first time users writing relatively simple modules, here are a few helpful tips:
 * Understand what the five main subroutines are for, especially {{{ProblemModuleInit}}} and {{{ProblemGridInit}}}
-* Know which variables come with {{{DataDeclarations}}}, {{{GlobalDeclarations}}}, and {{{PhysicsDeclarations}}} and which variables have to be defined by the user
-* Understand the form of the {{{q}}} array
+* Know which variables come with {{{DataDeclarations}}}, {{{GlobalDeclarations}}}, and {{{PhysicsDeclarations}}} and which variables must be defined in {{{problem.f90}}}
+* Understand the form of the {{{q}}} array, and also the {{{aux}}} array if using MHD
 * Make sure data is scaled so that only computational units are stored in the data arrays
-* It is often helpful to write a module that can run in 2D or 3D so pay close attention to how {{{nDim}}} affects variables
+* Since it is often useful to write a module that can run in 2D or 3D, pay close attention to how {{{nDim}}} affects variables
