# Add a site

Follow these steps to add your website or application to Cloudflare. Once your domain is active, your web traffic will proxy through Cloudflare, which speeds up and protects websites and services on your domain.

Cloudflare will become the primary DNS provider for your domain, meaning your DNS records are managed at Cloudflare, and we authoritatively answer all DNS queries.

To use Cloudflare, you need to own a domain (`example.com`

).

If you do not already own a domain name and plan to use Cloudflare for your authoritative DNS, we highly recommend purchasing your domain name through Cloudflare Registrar.

Using Cloudflare Registrar simplifies your setup process by automatically using Cloudflare for authoritative DNS.

If you are onboarding an existing domain to Cloudflare, make sure DNSSEC **is disabled** at your registrar (where you purchased your domain name). Otherwise, your domain will experience connectivity errors when you change your nameservers.

Provider-specific instructions


This is not an exhaustive list of how to update DS records in other providers, but the following links may be helpful:

Why you have to disable DNSSEC


When your domain has DNSSEC enabled ↗, your DNS provider digitally signs all your DNS records. This action prevents anyone else from issuing false DNS records on your behalf and redirecting traffic intended for your domain.

However, having a single set of signed records also prevents Cloudflare from issuing new DNS records on your behalf (which is part of using Cloudflare for your authoritative nameservers). So if you change your nameservers without disabling DNSSEC, DNSSEC will prevent Cloudflare's DNS records from resolving properly.

-
Log in to the Cloudflare dashboard ↗.

-
Select

**Add a domain**. -
Enter your website’s apex domain ('example.com'), choose how you would like to add your DNS records, and select

**Continue**. -
Select a plan ↗.

-
Make sure we have all of your DNS records.

When you add a new site to Cloudflare, Cloudflare automatically scans for common records and adds them to the DNS zone. The records show up under the respective zone

**DNS**>**Records**page.

-
Since this scan is not guaranteed to find all existing DNS records, you need to review your records, paying special attention to the following record types:

-
If you find any missing records, manually add those records.

-
Depending on your site setup, you may want to adjust the proxy status for certain

`A`

,`AAAA`

, or`CNAME`

records. -
Select

**Continue**.

Once you have added a domain (also known as a *zone*) to Cloudflare, that domain will receive two assigned authoritative nameservers.

Before your domain can begin using Cloudflare for DNS resolution, you need to add these nameservers at your registrar. Make sure DNSSEC **is disabled** at this point.

To prevent insecure connections and visitor browser errors, make sure you have SSL/TLS protection and go through the **Quick Start Guide** to improve security.
