Hardcoding custom field in Metadata

People of Pods,

I’m trying to find the best way to add my custom field (vlogger_name) to the meta-Data, not unlike how the authors name would show up. I also need it to link to:

https://www.mouseandcastle.com/media-artist/{@vlogger_name}/

I can’t tell if it’s an edit on single.php, and if so, how to use PODS to do it. I should be able to edit this just once, and not in various places, right?

Is there good, written documentation on using PODS custom field outputs in different places like this?

Thanks You!
