+# [!important]
+
+This package is based on [mlr](https://github.com/mlr-org/mlr) which itself is considered retired due to the newer [mlr3](https://mlr3.mlr-org.com/) package. 
+We suggest to use the new mlr3 framework from now on and the related package [mlr3oml](https://github.com/mlr-org/mlr3oml) to access information from OpenML.
