 # PGS Catalog utilities
 
+
+> [!IMPORTANT]
+> * In June 2024 this repository was archived (made read-only) and the code here deprecated
+> * The code was refactored and migrated to a new set of Python packages contained in the [pygscatalog repository](https://github.com/PGScatalog/pygscatalog)
+> * [The PGS Catalog Calculator v2-beta](https://github.com/PGScatalog/pgsc_calc/releases/tag/v2.0.0-beta) uses these new Python packages
+> * The Python package [pgscatalog-utils](https://pypi.org/project/pgscatalog-utils/) is unaffected by this change, and we will continue to publish updates from the new repository
+> * If you experience problems with our Python tools, please [create issues at the new repository](https://github.com/PGScatalog/pygscatalog/issues/new)
