 [MLJ](https://juliaml.ai) (Machine Learning in Julia) is a suite of Julia software
-packages providing a machine learning toolbox. The *MLJ Model Registry*, a list of
-packages providing MLJ interfaces to machine learning algorithms, together with metadata
-about those models, such as the type of data models can operate on, and their document
-strings. This package provides software tools for MLJ maintainers to manage the Model
-Registry, for example to add the models provided by a new machine learning package

 distribution) and lives in [this
