If you elect to use a custom hostname for your changelog page, you will need to set it on your Public Feed settings first.
After setting the custom hostname (eg changelog.mysite.com) you need to point the DNS records of this hostname to our servers.
In order to point the hostname, please create a CNAME record targeting cname.announcekit.app
changelog.mysite.com CNAME cname.announcekit.app.
We automatically create SSL certificates for the custom domains without any steps required from you. Just create the CNAME record and leave the rest to us.
If you want your Custom hosted public feed to recognize Segmentation rules and enable User Tracking, please get the updated widget code from the Dashboard and update it on your web page.
