 ## Content Security Policy (CSP)
 
 The default distribution bundle of the WebComponent includes styles and the worker in a single file. This might cause issues with strict CSP rules. If you require strict CSP compliance, consider using the scripts located in the `/dist_external` directory. For more details, please refer to the [documentation](https://altcha.org/docs/website-integration).
