download "how to" help guides

The help articles have a printer icon at the top right of your screen. You can print any pages you think would be helpful to you. If your new to Marketo, I'd start with the 11 articles on this page. The articles in the roadmap to becoming a Marketo Certified Expert are helpful as well. You can find that guide here.

I have written extensive help documentation for marketrs here:

There is no downloadable guide here on the community other than guides for the Integration and Webinar Providers.
