+## DEPRECATION/MIGRATION WARNING:
+
+This package has been replaced by [scBoolSeq](https://github.com/bnediction/scBoolSeq) which implements the generation of synthetic scRNA-Seq data biased by Boolean activation states as well as rich CLI. If any of your work relies on `profile_binr`, we invite you to migrate to `scBoolSeq` which has retained a similar API but has a richer set of features.
