 Support for `DataFrames.jl` minilanguage and operations is planned for the `DTable`
 to enable a seemless transition between in-memory and distributed data processing.
 
-As of today `select` is available with more operations to come in the future.
+As of today `select`, `transform` and `combine` are available with more operations to come in the future.
+You can use the exact same DataFrames.jl minilanguage when using these operations.
 
 The goal is to provide exactly the same output as for DataFrames using the same `args`.
 Even though the output should be the same the DTable may require modification of user input in order to provide optimal distributed performance.
 
 One already known tactic is to avoid functions that require access to the full column at once.
 The user should prefer to use `ByRow` equivalents or `reduce` instead.
-A complete performance guide will surely be a part of the documentation at some point.
