I just got my Cloudflare account, what can I do with it?
If you just activated Cloudflare through your control panel, a new Cloudflare account will be created for you with the same e-mail address you used to sign up with us. After your domain name has been added to Cloudflare, you'll receive an e-mail with a link to set your password.
Through the Cloudflare website, you can view your Cloudflare analytics, change caching and security settings and enable Cloudflare apps. The only thing you can't do through Cloudflare is change your DNS records. Your domain name is still controlled through our nameservers so any nameserver changes need to be done through our control panel.
If you have your own domain name and want to manage your DNS through Cloudflare, that's possible as well. To do that, first disable Cloudflare through our control panel, then login to your Cloudflare account and add your domain through there. Cloudflare will scan our nameservers and set the appropriate records for your domain. They will also give you two nameservers which you need to set for your domain name through your registrar instead of our nameservers.
Note that if you're using Cloudflare directly, the DNS settings in our control panel (like MX Records and CNAME Records) won't work anymore for your domain. If you want to create subdomains of your Cloudflare controlled domain, you will also need to create a DNS record for those (a CNAME record pointing to your root domain is the easiest way to set it up).
