Activating Spanish Language

Summary:

Hello,

I posted about activating languages previously but I'm hoping to get some more eyes on this, specifically activating Spanish.

Has anyone activated Spanish in their zones and would be willing to walk me through your process?

Content (required):

I've read that it starts with having Oracle activate the language but there are notes around not being able to remove this once it's done, so I'm cautious. I assume if we activated this in staging, though, that a refresh from production would remove it if needed?

What comes after that? I understand that some delivered content is translated automatically but custom content has to be reviewed and translated on its own. What does that look like? How is this reviewed?
