+        Instructions to add your own domain
+      %hr
+      %p
+        When you created the conference, the conference splash page is available in the following domain:
+        %strong
+          osem.io/conferences/#{@conference.short_title}
+      %p
+        However, we also provide support for hosting conferences on your own domain.
+
+        Terms to get familiar with:
+      %p
+        %strong
+          Domain registrar:
+        Domain registrar is just another term used for providers who work on reserving domain names.
+      %p
+        %strong
+          CNAME:
+        A Canonical Name record is a resource used which defines that your domain name is an alias for another domain name.
+      %p
+        To add your own domain you can follow these 
+        %i
+          three
+        steps:
+      %ol
+        %li
+          Pick a domain you want to host your conference on from a domain registrar or register it with a domain registrar.
+        %li
+          Add your own domain name to OSEM ( link to conference/custom_domain#create ) and select the conference it should belong to.
+        %li
+          The last step is adding a CNAME record in your registrar’s DNS Settings. Different registrars have different ways of adding a CNAME record. The following guides would help you setup a CNAME record depending upon the registrar of your domain. If it doesn’t, you probably should get in touch with your domain registrar and ask him how to register a CNAME record in their platform.
