Microsoft Word macro

I'm looking for help with creating a simple MS Word macro to add a block of text in the place where the cursor is pointed when running the macro, to add a table or a block of text (I don't know which one is better). Upon running a macro there should be a prompt asking user: "Insert DocuSign signature block?" "Yes"/"No". The part to be added by the macro is attached. Before inserting the new signature block, check whether the document already has text that matches “//<anything>//.” If so, throw warning message, “This document appears to have DocuSign codes already. Add DocuSign signature block? No Yes” If user chooses no, close the macro.
