 ## Prerequisites
 
-Before proceeding with the Pages configuration, you will need to:
-
-1. Have a separate domain under which the GitLab Pages will be served. In this
-   document we assume that to be `example.io`.
-1. Configure a **wildcard DNS record**.
-1. (Optional) Have a **wildcard certificate** for that domain if you decide to
-   serve Pages under HTTPS.
-1. (Optional but recommended) Enable [Shared runners](../../ci/runners/README.md)
-   so that your users don't have to bring their own.
-
-### DNS configuration
-
-GitLab Pages expect to run on their own virtual host. In your DNS server/provider
-you need to add a [wildcard DNS A record][wiki-wildcard-dns] pointing to the
-host that GitLab runs. For example, an entry would look like this:
-
-```
-*.example.io. 1800 IN A 1.1.1.1
-```
-
-where `example.io` is the domain under which GitLab Pages will be served
-and `1.1.1.1` is the IP address of your GitLab instance.

-You should not use the GitLab domain to serve user pages. For more information
