+In order to reduce the time taken by `using MLDatasets` in users' code,
 we use a [lazy import system](https://github.com/johnnychen94/LazyModules.jl) that defers the import of packages inside MLDatasets.jl as much as possible.  
-For some of the packages like (e.g. `DataFrames.jl`) some manual intervention is needed from the user.
