Cloudflare adds a free CDN, caching, and security in front of your site.

1. Create a free account at Cloudflare and add your domain.
2. Cloudflare scans and imports your existing DNS records — check they all came across correctly (especially your A and MX records).
3. Cloudflare gives you two nameservers. Update your domain's nameservers (article 129) to those Cloudflare values at your registrar.
4. Wait for Cloudflare to confirm activation (can take a few hours).
5. Manage all DNS records in the Cloudflare dashboard from now on (not cPanel's Zone Editor).

Important: Once you switch to Cloudflare's nameservers, your DNS is managed at Cloudflare — make future record changes there. Keep your email's MX and related records intact during the move, or mail will stop flowing.
