Does PMI (or the wider group) have a documentation set that is used to initiate a portfolio, that would define the structure, governance etc.? Saving Changes...
You can look at the Portfolio Management Standard but if you want specific examples or templates, I'd recommend first understanding the information and governance needs of your senior stakeholders and then look at some examples from the Templates section of this community as a starting point.

There is no set template, you can customize a document to suit your portfolio needs so just like Kiron suggested, it would be best if you review the standard, it will give you a great idea. Saving Changes...
