If you own a domain, you can use it as the address for your liturgical website.
Here are the steps to take.
Gitlab will then show you a verification code, e.g.:
_gitlab-pages-verification-code.chapel.liml.org TXT gitlab-pages-verification-code=f1d6f29318d7065d7b26df154472c819
In the above example, it is a verification for chapel.liml.org, a (fictitious) subdomain for liml.org.
Next, log onto the website you use to manage the DNS settings for your domain.
Create a text record. The host name is the part of the verification code before TXT. The text value is the part after TXT. In other words, don’t include the TXT itself.
