You do not have to learn anything new. Opal does the looking, and you do the deciding.
She looks every day.
Once you connect your site, Opal checks it each day: is it up, is the certificate good, do the links work, is anything slow or out of date. You do not have to be there.
She tells you in plain words.
When something needs a look, she writes it the way a friend would. “A link goes nowhere.” Not a wall of codes.
She asks before she changes anything.
Small fixes are her job, but they are your site. She shows you what she wants to do, you say yes, and then she tells you what she did.
