Adding and Formatting Text in Google Docs Script Editor

[Hampoon]

Hi there. I'm brand new to this whole script editor thing, and I would like to know how I can insert text into a document, change its font, font size, and add it to a header. 

I really have no idea what I'm doing, so please try to explain everything well. :P

.setHeading(DocumentApp.ParagraphHeading.HEADING1);
