+!!! warning
+    `AutoEnzyme` can be used by [DifferentiationInterface.jl](https://github.com/JuliaDiff/DifferentiationInterface.jl) to access a restricted subset of Enzyme.jl functionality.
+    If your code or one of its dependencies computes derivatives through DifferentiationInterface.jl, you might experience slowdowns or errors that would not happen with Enzyme.jl's native API.
+    In that case, please refer to the [Enzyme.jl documentation](https://enzymead.github.io/Enzyme.jl/stable/) for details on how to call its native API.
