 Built for machine learning practitioners requiring flexible and robust hyperparameter tuning, **ConfOpt** delivers superior optimization performance through conformal uncertainty quantification and a wide selection of surrogate models.
 
+**ConfOpt** also lends itself well to HPO research and as an add-on, requiring limited [dependancies](https://github.com/rick12000/confopt/blob/main/requirements.txt) and focusing on pure search methodology.

+## 🔗 Integrations
+
+Advanced users should note **ConfOpt** doesn't currently support parallelization, multi-fidelity optimization and multi-objective optimization.
+
+If you wish to use **ConfOpt** with parallelization or multi-fidelity/pruning, fear not, there's an [Optuna](https://github.com/optuna) integration that supports both. Parallelization support has been well tested, while multi-fidelity/pruning is still experimental (it should work well and has been spot tested, but if there are any problems please raise an issue).
+
+For instructions on how to use **ConfOpt** in Optuna refer to the official documentation [here](https://hub.optuna.org/samplers/confopt_sampler/).
