Once you have subscribed to a paid plan, you can setup your own custom domain. Setting up custom domain mapping is a two step process. The first step will be to add CNAME record in your domain service provider Cpanel(or DNS mapping). You can refer to this link for adding CNAME record: http://support.learnyst.com/manage-your-custom-domain-url/setting-up-custom-domain/introduction
The second step will be to setup your own custom domain from the Learnyst admin panel:
Firstly, log in to your Learnyst account as an admin.
Now, click on “Settings” as shown below.
Now, click on “Custom Domain” and enter your custom domain in the space provided as shown below. Finally, click on “Add Domain” as shown below.
NOTE: You cannot edit your custom domain once added. Hence, please make sure that you enter the custom domain carefully.
