 # Scikit-Learn Wrapper for Keras
 
+> [!WARNING]  
+> This project is now deprecated. Keras has re-introduced wrappers with a similar API to those in SciKeras, but they will be better maintained.
+> SciKeras was a project to meet a specific need that was developed by a single developer.
+> I no longer use Keras nor do I have the time to maintain this project, which became increasingly difficult with multiple versions of Keras and Scikit-Learn to support.
+> I thank all of the users and contributors over the years and hope that the new Keras wrappers will meet your needs.
+> TODO: add link to Keras docs and release here.
