+## Parameter list
+
+We curate a list of available pre-defined parameters here: @ref parameterlist.txt.
+
+Note that not all listed parameters will be available in all types of simulations. For example, naturally, the Newton
+solver can only be configured (via parameters in the group `[Newton]`) for
+simulations that actually use a Newton solver. Model-specific parameters are only
+read and used when the corresponding model is in use.
