 # Theoretical Basis for GEOPHIRES
 
-> **Document Status: Historical (v2.0)**
->
-> This document is adapted from the 2019 paper, "[GEOPHIRES v2.0: updated geothermal techno-economic simulation tool](https://doi.org/10.1186/s40517-019-0119-6)" by Koenraad Beckers & Kevin McCabe.
->
-> The core theoretical explanations and equations herein have **not** been revised and reflect that version. While the lists of models have been minimally updated to link to newer documentation, the underlying theory for those additions is **not** described here. For the most accurate and up-to-date information, please consult the primary [project documentation](https://github.com/NREL/GEOPHIRES-X?tab=readme-ov-file#documentation).
+This document describes the foundational theoretical basis for GEOPHIRES, adapted from the 2019 paper, "[GEOPHIRES v2.0: updated geothermal techno-economic simulation tool](https://doi.org/10.1186/s40517-019-0119-6)". The core theories described here remain valid and relevant to the current software.
+
+However, the text has not been comprehensively updated to include the theory for features added in GEOPHIRES v3 (GEOPHIRES-X) and later.
+While pointers to the documentation for newer models have been added, the detailed technical descriptions herein still pertain to v2.0.
+For a complete and current reference, please see the [README](https://github.com/NREL/GEOPHIRES-X?tab=readme-ov-file#documentation).
