+# FAQ
+
+Welcome to the FAQ for Namingo. This document is intended as a resource for registries to share with their registrars, providing answers to common questions and guidance on managing registrar accounts.
+
+## General Information
+
+- **Configuration Access**: All configurations of a registrar account are managed via the control panel. Registrars can choose to manage their customers through the panel or via EPP (Extensible Provisioning Protocol).
+- **SSL Requirement**: Access to the registry requires an SSL certificate. Any valid SSL certificate will work.
+
+## Tools and Modules
+
+- **EPP Client**: We provide an EPP client in PHP available at [Tembo EPP Client](https://github.com/getpinga/tembo).
+- **WHMCS Module**: For integration with WHMCS, use our module available at [WHMCS EPP RFC](https://github.com/getpinga/whmcs-epp-rfc).
+- **FOSSBilling Module**: For FOSSBilling integration, refer to [FOSSBilling EPP RFC](https://github.com/getpinga/fossbilling-epp-rfc).
+- **Compatibility**: All other EPP clients that support RFC-compliant EPP will also work with our system.
