-## Testing models in a new MLJ model interface implementation
-
-The following tests the model interface implemented by some model type `MyClassifier` for
-multiclass classification, as might appear in tests for a package providing that type:
-
-```julia
-import MLJTestIntegration
-using Test
-X, y = MLJTestIntegration.make_multiclass()
-failures, summary = MLJTestIntegration.test([MyClassifier, ], X, y, verbosity=1, mod=@__MODULE__)
-@test isempty(failures)
-```

-## Testing models after filtering models in the registry
+# Example: Testing models filtered from the MLJ model registry
 
 The following applies comprehensive integration tests to all
 regressors provided by the package GLM.jl appearing in the MLJ Model
