# Custom domains

Before start prepare your custom domain on the provider's side (any web hosting), for example, mydomain.com. Then, create a subdomain for the primary domain: example.mydomain.com and set up CNAME to r.trwl1.com

Then go to the **Settings - Custom domains** tab in Trackwill. You will see all default domains assigned to your account:

![](/files/-LvJHd4-0eauCJnKdGmH)

Then click Add button:

![](/files/-LvJJfiE4f8ykI8B628I)

And type you custom domain URL and click **Add domain** button:

![](/files/-LvJK2NA8qNbfVtWluRm)

After that select your custom domains as a main domain here:
