Adding library information to document template, is it possible?

Hi,

I am working in a request that involve library template and library columns. 

The request is create a template that show the name of the user that created the document and when.

I have look different approachs but nothing works. 

Right now I have a custom template with nothing but standard information: Header, logo, a footer showing who created the word template and when.

Now I need to add who created the document in sharepoint and when. In the Quick parts of the template I can't find the columns I need from the document library. 

My other approach was follow this blog but I can't use [] in the name of the column and I don't even know if it will work.

 

Has anyone created this kind of word templates that can give me a hand with it?

 

Best regards
