# Simplest way to typeset entire document in sans serif (Helvetica)

How do I typeset an entire document in Helvetica/sans serif without littering the document with font changes for every heading/paragraph, etc.? Like this but with the paragraphs all in Helvetica.

For example, I've seen documents typeset in Computer Modern and then switched to Palatino, but can I do the same with Helvetica with a few commands at the beginning?

(And please don't tell me to use a serif font for body copy / paragraphs. I know. I'm trying to use latex to typeset my resume to look like the one I've created in a word processor, which is hard to maintain but looks good. I'm hoping latex will let me do more advanced formatting/layout, separating content from form.)
