+## Feature Compatibility

+Before diving into parameter details, check the **[Feature Compatibility Guide](case_constraints.md)** to understand:
+- Which features work together (MHD, bubbles, phase change, etc.)
+- Common configuration patterns with copy-paste examples
+- Requirements for each model equation and Riemann solver
+
+💡 **Tip:** If you get a validation error, the compatibility guide explains what each parameter requires.

 There are multiple sets of parameters that must be specified in the python input file:

 2. [Computational Domain Parameters](#2-computational-domain)
