How do I point my domain to Cloudflare before connecting it to Squarespace?

Before connecting your domain to Squarespace, you need to transfer your domain's nameservers to Cloudflare. This tells the internet to look to Cloudflare for DNS information. Log in to your domain registrar (where you purchased your domain – GoDaddy, Namecheap, etc.) and find the section for managing nameservers. Replace the existing nameservers with the ones provided by Cloudflare. It can take 24-48 hours for these changes to propagate across the internet.
