 - **User Interface (UI):** Development of a graphical user interface (GUI) for easier and more intuitive interaction with Profilarr. This UI will cater to users who prefer graphical over command-line interactions.
 - **Automatic Updates:** Implement an auto-update mechanism for Profilarr, ensuring users always have access to the latest features, improvements, and bug fixes without manual intervention.
 
+## Known Issues
+- You may encounter a `JSON Encode Error`. This occurs when the base_url is entered incorrectly. Measures have been taken to prevent this, but if you encounter this error, please check your base_url in the config.yml file.
+
 ## Contributing
 
 - I've added a docker compose file for testing custom formats / quality profiles. Run `docker-compose up -d` to start the Radarr/ Sonarr test containers. Add your API keys to the `config.yml` file and begin testing!
