If you're trying to add a subdomain, which is a domain name in this format - kevin.yourdomain.com
(You'll be replacing "kevin" and "yourdomain.com" with your respective subdomain).
Then you're at the right place!
Words of warning (please read)
1 - Please note that www won't work in front of your subdomain.
2 - Also note that if you're trying to add a top-level domain (www.yourdomain.com instead of subdomain.yourdomain.com), then go here.
1) Add a CNAME record at your domain registrar (like Godaddy)
First find, the DNS management section of your registrar. Depending on which registrar you use, you might need to take some time to find this section.
Set a CNAME for the first part of your subdomain to point to us
This is what that looks like in a registrar like Godaddy (other registrars will have a similar-looking box).
^ Remember you replace "kevin" with whatever subdomain you're trying to add.
For example - let's say you wanted to create a subdomain like members.yourdomain.com
Then you would type in "members" in this box.
2) Go back into your project settings, and verify you added the subdomain correctly
You access this page by going to the "settings" on the left navigation menu.
Press the check domain settings button.
3) If the subdomain is verified, you're good to go, however, you may still need to wait for 24h while our SSL certificate gets issued.
It takes a little while for our system to finish issuing the SSL certificate. So if you see an error after your domain is verified, this is normal.
Please contact us only if the error is still there after 24 hours from set up.
