The one line of code will get you all of the form elements values in the email message. If you want to have more control over the contents of the body you can use the bindings to just drag and drop the values into the message where you would like to see them.
Sorry, the archived docs link is on the right side of the page, not the left. My bad.
The links I posted are live links to these docs, we do not have a pdf for these, just the videos. Is there a specific part of the process that you are having a hard time with? Please post back with any questions that you have.
